It is so good that you faced your fears and went out alone. Don't give up .. try it again. I was a professor at a university and started having panic attacks when teaching and had to go on disability. Even going to the university put me into a panic attack. Finally, there was a course I wanted to take at a community college. I went and when I went into the room I started having a panic attack. I stayed. Every time I went to the class it got better and better. Now I am just a bit anxious in a classroom. I don't think I can go back to teaching but I could take another course. It gets better.
