I'm very lonely? what to do?

i am so annoyed, depressed and confused!

so at school I've been trying to fit in

you know talk more, quit excluding myself

so people will let me join in but in the hallways they don't even acknowledge me, and in some cases I just don't fit in

like its really hard going through high school with no friends no one to run to when you feel troubled, my family doesn't understand or don't care when I tell them, and if I tell someone at school they will me fun of me I feel so lonely:(!
