Don't have time to post a lot but this is probably the most honest you've been about your feelings. That's a good think. Now think about how scary this is compared to other things in life.
Start getting into things now and you won't have to worry about the fall. And don't worry about it now, (I know, you're a worrier) Don't borrow trouble. Don't choose activities that go against your personality)if you're an introvert don't do things that involve 50 people, because you won't keep it up.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
