Scared of sleep please help me?

This is some pretty serious stuff. Clearly you have some deep seeded fears that you have never resolved. Perhaps something traumatic happened in your life that you have yet to work through. How is your family life? Whenever Im stressed I turn to my family, as a close relationship with your parents and siblings are the strong bonds i have and these are the people you will be able to depend on for the rest of your life. Also, does your anxiety stem from school based pressure. If so, you need to be honest and open with the people around, mainly your parents,and not hide your fears, as that will only escalate your problem. I think another very easy to step you could take to improve your situation would be to try to gain weight, so you can take your medication properly. Why do you have a eating disorder? Is it because you feel self-conscience and not pretty, because if so that is foolish and by not eating properly your doing more harm than good for your looks. I know so many beautiful girls that think by being as thin as possible they will look better, but trust me as a guy, we like girls with curves. Im no psychiatrist but I have been able to work through many problems with friends, and sometimes its the little support that can help the most. Good luck with your situation, and I hope you are able to find peace and stability in your life.
