Hey Matt.

I know how difficult it is to be in a situation of anxiety and be completely confused by it. I went to my school counselor and she said I could have OCD, GAD, and Social Anxiety... even though I disagree about the last one.

Personally, I think you should go back to a therapist and this time try to talk. I now it must be hard, but holding back isnt helping you. You can already see that.

Secondly, I think that you need to at least give medications a try. Talk with a doctor first to see if there is any psychotherapy you can do, but if that doesn't help, you should really give it a shot. I know how your parents must feel about you being on it, because I use to feel the exact same way, but I have gotten to the point of worrying so much, that I feel like I need to have medication help get my mind right. If they don't like they way it effects you, you could always pull away from it.

About your girlfriend, does she know about your anxiety? If not, I think it would only be fair to let her in, if only slightly. That way she understands when you blow her off and maybe you two can try to work around it. And don't worry about disappointing her. I am sure you wont and if for some reason you do, then you'll find someone else (even though I know hearing things like that aren't always the most helpful).

Hang in there. You'll be fine.
Good Luck.
