I'm accueil schooled so I don't have very many friends. I'm lonely. What should I do?

im not accueil schoold but im lonely as hell.... when im with my friends... is like i dont exist cuz they r always talking with some one else... waht i do is go to site like this ou Facebook ou twitter and chat with ppl.... some ppl i dont even know... but dont do that... i think the better thing to do is go out and try to meet ppl... i dont cuz i cant go out much and im to chiken shit :( but that would probably change once i get out of this place.... (im moving) that is.. if i dont screw that up par getting bad grades (right now i think my dad is gonna kill me cuz i didnt turn in my projects)...
:/
