There is free online public schools. One is K12, they send you all your books, most materials, a computer, printer (if you don't have one), art supplies, microscope...you just have to have an internet connection pretty much. You work at your pace and can actually be ahead. Look it up, very good program.
What are u scared of exactly? If u don't want to talk to an official councler then talk to a close friend or somebody who cares about u and ur issue. U could talk to me if u have nobodyelse.
What exactly are you afraid about? Just the whole concept of school? Some highschools have online classes for students to take. Check into that, it might help you get away. If you want help to be able to go to school unafraid, go seek a conselor or as such, they can help tons.
