I could be feeling okay at school but there's like times when I don't know what to do. It's very stupid but for example...like if I finished my work and I have to turn it in to the teacher and she's busy, I won't interrupt her and wait until she's finished but that gets me anxious and I don't know what to do. When I am going to get the bus it gets me nervous. When I walk in front of people it kind of gets me nervous too.

I am in high school and I'm just afraid of what college might be. I'm afraid of acting awkward and feeling extremely shy.It doesn't happen always , but only when I think of it. I think it might be due to this anxiety disorder that I have but I really don't know and just by thinking about it I start shaking...
any ideas on why i feel like this and how can i get rid of this feeling ?
