Hello noonehome, It's good that you posted here for support. You have gotten some good advise here. Magnum was totally right about your friend. You may need additional support through a school counceller or a therapist. Someone that you can have face to face interaction with. It's tough to go it at such a young age, but you can use that to your advantage. Make changes and live your life as you want. You get only one chance, use the gifts God gave you and enjoy your life to the full. It seems like many of us, lack self confidence. Take one step at a time. Finish schooling. Get a job. Keep in control and move ahead. When you loose control, panic can set it. BREATHE. Make plans, become enpowered by sticking to those plans.
There was a book that helped me: Feel the Fear . . . and Do It Anyway by Susan Jeffers. It also comes in an autobook.
Hugs, 4thgen
