I think everyone hates me?

It's actually gotten to the point where i can't do this anymore. I've lost my apitite, i cant even be bothered to do my homework....

the guy i like in my class, who knows i like him, is acting like a total douchebag to me. He just gave me these evil stares today and was 'shifty' around me. He never used to be like that.

i accidentily deleted a guy i knows saved nintendo game during break. He was upset although i apologised. my friend told me that in english class he was still upset by it.

My OTHER friend stopped speaking to me about a month ago when my grandmother was hospitalised (shes much better now.)

I'm failing everything in school except for English.

The guy I like doesnt like me back. and to top it all off, i think he likes this girl Cecelia who doesnt like him back (Shes one of those pretty types who doesnt realise guys fawn over her)

I feel totally isolated from everyone else i'd consider a friend. the only thing i can be bothered to get up in the morning for is the book im writing.

i really dont know what to do. I genuinely feel confused, upset and on the threshold of depression. im only 17, and in high school
