I'm really sorry you are feeling this way. I've had feeling of anxiety before; I can say the feeling is not a good one! When I am feeling that way I remove myself from what is making me feel that way. I know sometimes that's hard to do. First of all, you can't worry about what people think. I know that's easier said than done, but they are no better then you. Once you start liking yourself others will too, people like confidence (like dogs that smell fear, people smell weakness) keep your head up and sholders back. You have a great accomplishment you should be proud of! It's absolutely great that you lost all that weight! That is an inspiration in itself! Do you work out with weights at all? Also another think to consider sometimes women can be catty when their jelious. It's also a possibility that girl was not talking about you.

I agree with 50guy, hobbies helps ("idle hands are the devils advocate"). Keep busy, busy, busy don't leave your mind time to destroy itself.

Take care and try to find a different pharmacy.
