Highschool to College

Wasnt sure where to talk about this, or where to post it. Im a bit embarrassed to talk to my friends, I dont think theyd really understand. Im not even sure whats going on with me...

To start with, Ive always had performance anxiety. In high school, whenever I had to present, my IBS would kick in full swing and Id be on the toilet for 15 minutes. That was nothing. I also have social anxiety, which I never realized till now. I cant stop talking in social situations, and I guess its my way of filling the gap.

Now Im going to college, and I need help.. Recently my anxiety has worsened, and I never really realized how bad it was until I had a near panic attack on the plane. I was going to orientation, and the plane was three hours late, and I was extremely stressed out. I had to lay down on my moms lap to feel better. Now I have a fear of planes, so much so that I never want to go on one again, and all I can do is worry. I stopped going out as much, all I do is watch TV. And whenever I think about college my IBS kicks in again. I cant stop, and lately I dont feel like myself either. Im okay when Im with friends or distracted, but once Im alone with my thoughts, I just feel sad. I feel like I never knew who I really was, and I dont know what the point in being here is. I have to remind myself of who I am.

Ive even gotten weird neck pains and breathing pains, which went away, but still caused even more worry.

I dont know what to do.
