Welcome to the board Amy,
You're not a failure at all. At your age to be that successfull with schooling, that's incredible. I'm currently in school and I'm 22, I've been diagnosed with Social Anxiety so school is pretty tough for me right now, I'm also on 50mg sertraline (just started, next psych appointment in two days) and 's kicing my butt. I'm sorry to hear your anxiety has come back but you sound like a strong individual in means of getting a grip on it. I want you to know that you're not alone, It's hard to talk to people and it gets easy to build up.... but just know that people here in this board DO listen, and we will provide you support.
It's amazing and sad how anxiety snowball effects into more and more problems... that we shouldn't be worrying about normally. Never set limits on yourself, you sound like a great person. I hope to hear from you.
How is your medication going for you? I can't wait to start my therapy on the 27th.
Keep us posted and post around.
