My suspicions are that you do not have an eating disorder (namely anorexia nervosa or bulemia nervosa).
 

I don't know a great deal about you, so I can't say definitively whether or not you would meet criteria for these disorders.
 

There have been a few studies with heterosexuals vs homosexuals and eating disorders, and it has shown that gay men and straight women tend to have eating disorders more often than straight men and lesbians. The theory is, lesbians may not be as susceptible to eating disorders because they tend to not be as concerned with physical appearance (in terms of attraction). The ideals of what a woman "should" look like have been constructed from a male perspective. It would make sense that if you are sexually attracted to men, you'd be more susceptible to what a man's "ideal" woman "should" look like. 
 Considering 90% of eating disorder clients are women, it stands to reason that eating disorders can and do affect lesbians as well, because lesbians are first and foremost women (and the sexual identity is just one part of who they are).  Research has also shown, that lesbians may be at an overall greater health risk because of higher BMI (body mass index). Women with higher BMI have poorer body image.

Body image is highly correlated with self-esteem. I suspect this is where you're at right now. While (theoretically) you as a lesbian may be somewhat protected from societal/cultural messages regarding appearance, there's a whole hell of a lot of other  mental health consequences that come from belonging to a stigmatized minority group (being gay/lesbian in a predominantly straight world).

Considering you have an anxiety disorder, compounded with a mild form of OCD (which is also an anxiety disorder), it stands to reason that this fixation on weight and food could be a part of the anxiety disorders. Furthermore, it could also be a symptom of Depression, which is highly common with anxiety disorders.

I suggest that you bring this up with a therapist (I don't know if you are seeing that one therapist that you mentioned in a different post). In the mean time, I'd as myself "Why now?" Why are you having this issue with weight and eating now, instead of a year ago, or a week from now?

Give me about like 5 pounds or so and I'm obese according to bmi. I tell you, no joke...get into lifting heavy weights and it will make you smaller at first for quite awhile. Then you could just stop going as heavy...and you can eat whatever you want. no joke.-in terms of appearance lol...not saying fast food won't clog your arteries no matter how hard you workout lol. muscle burns fat when you do nothing! which for me I like still, and used to like even more lol just uh...food for thought lol best of luck!

Gladiatorgirl just brought up a good point about BMI - it's a bit sketchy!  BMI just reflects height and weight measures and doesn't account for body composition. Therefore, it's highly possible for atheletic people to be classified as overweight (per the BMI scale) but not overfat.

well according to BMI I am highly overweight / obese.
now Ive just depressed myself.
:(
ah well..

Well then, you have a choice to make: You can either choose to be self-destructive and be depressed, or you can take control of your life and make mentally/physically healthy choices. Which person do you want to be?

Ahhh you sound like my therapist....
Last session she asked me who I am, and due to my social anxiety because Ive spent most of my life trying to be who everyone wants me to be I dont know, But I do eat healthily, and I exercise, you dont have to worry about me there.
I may not be happy with what I see, but I do look after it.
no worries there.

Haha, no surprise that I may sound like a therapist :p

Good news is, if you're eating right and exercising regularly, you're body will be the shape it's supposed to be. 

I can just imagine how much happier you'll be if/when you aren't concerned with the person everyone else wants you to be.

I'll start out by telling you this: You may be clinically diagnosed as having GAD but you are NOT (and I repeat NOT) your disorder. You are a person with anxiety, but you do not have to be characterized by that. It may affect the way you interact with the life, but it does not have to become your life or dominate your life.

[just a little bit of my background info: I worked for 4 years on an adult inpatient psychiatric unit and for a year on an adolescent inpatient unit]     I have seen in so many people for many years who embodied the disorder that was labeled to them. They gave up any hope of managing their illness or living a healthy productive life, and instead accepted the disorder as who they are.

It may sound like I'm doing nothing but playing word games here, but I assure you, both are mindsets you choose to adopt. You're either an anxious person, or a person who lives with an anxiety disorder.

;) just a little food for thought

well, first thing, my therapist said i have SOCIAL ANXIETY not GAD (which my doctor diagnosed) and I am feeling a little better that i have the correct diagnosis now because when I looked up GAD it didnt fit with me, but when i looked up social anxiety I ticked the boxes so to speak, and as I have a correct diagnosis I am recieving the correct coping techniques and such. I have noticed subtle changes here and there, and I am on a better track than I was.
 
If I didnt have my partner, I know i would be worse off, she is my security blanket and i feel comfortable around her, so i go out more and such when she is home.
so now i have to learn to cope the same without her, and thats hard, I go to work on the bus and although its only a 20 min bus ride i am soaked through with sweat and shaking when i get off the bus, I work for 3 hours then come home, and thats more than enough for me..

my therapist thought that it is interesting that I am terrified of people yet i work in a people related job (retail) and I am studying to be a physiotherapist, and I also have 6 years nursing experience behind me, but as i explained to her, got to the stage 2 years ago where I was NOT functioning, thats why I left nursing, me working 12 hours a week and studying via correspondance is all I can manage, but it is a HUGE improvement, I am proud of where I am right now.

(recieving the right help is 90% of the reason I am at this stage)

and while i am on that note, if you ever recieve a diagnosis for ANYTHING and it doesnt feel right, please seek a 2nd opinion, if I had done that , who knows where i would be, I have spent my life being misdiagnosed by doctors who never sent me to mental health, I admitted myself and recieved a correct diagnosis and the correct help.

Listen to your intuitution.  and your loved ones.

You hit the nail on the head!

You know, if a doctor told you that you had cancer and it was terminal, you'd probably get a second opinion. If a doctor told you that you would have to undergo an extremely long and risky surgery to cure an illness you had, you would probably get a second opinion.

There is absolutely NOTHING wrong with getting a second opinion from a different psychiatrist/therapist whenever you are diagnosed by another(and it is SO important that it is a psychiatrist or other mental health professional who does the diagnosing, because general practitioners like your family doctor or pediatrician really aren't qualified to make that judgement). A mental illness (or any mental issue for that matter, specifically personality disorders, or anything that has "disorder" at the end of it) is a life changing diagnosis that shouldn't be taken lightly. If medications are going to be used to manage it, it is super important that the right diagnosis is established, otherwise, the meds are not going to work, and could possibly make it worse (ie: using anti-depressants with someone with bipolar). 

 Excellent point you brought up!

Keep working on the coping skills. Having a support system (ie: your partner) is already a very good coping skill that seems to have helped you out tremendously.

*grins happily*

My friends and I forced a girl we knew to get bulimia treatment she was getting really bad and in complete denial about her problem, if you know someone who has an eating disorder i would step in and help them no different then if they started to abuse drugs.

Well have you ever thought about binge eating disorder? That would only be if you go out and eat all kinds of junk food regulary. Even if every other week.
There are all kinds of disordered types of eating that come off of the normal anorexia nervosa and bulimia nervosa you hear about all the time.
Binge Eating Disorder would be anything from starving yourself to eating totally normally but completely binging on everything regularly.

You got that right, it's the beginning of an eating disorder and I think you should find a good nutritionist to guide you out of this. Also I sense some pessimism in you words, you probably also suffer from anxiety and that something you also fix with good nutritional habits. If that doesn't work either then you can review few eating disorders programs just in case you think things go worse.

My sister had an eating disorder throughout half of her life, it was one of the hardest things i've gone through and have seen her gone through. I say it is normal to be unhappy with your body at certain times in your life but hey, if your partner fell in love with you with your body then I say there is nothing disgusting about you. You can't just jump into losing weight and changing your body, find things you love about your body and just plainly about yourself. If you are happy with how you are then talk to your partner or a friend and get HEALTHY and FIT NOT SKINNY. You were made the way you were the only thing you can do is change your health not your body size. I hope you nothing but the best and hope this helped in any tiny bit, don't give up on your self your beautiful and an amazing person! :)
