I need to get this out....

Im so depressed atm!! everythings going wrong....
My best friend is being all weird and not really talking to me- she's made friends with these other 2 girls who i knew at primary school, they're ok but i dont want to get too close to them incase they hurt me again... my 'friends' decided i was skiving and are now acting like i dont exist and leave me out, and i feel like everyone hates me and they'd be better off without me....
plus we've got exams next week and im too stressed and upset to revise properly, trying to do gcse coursework atm but i cant focus :'(
also there's this boy i REALLY like who goes on my bus and he acts like he likes me but im too shy to do anything....like one day he'll talk to me all the way home about drums and stuff, the next he'll go off with someone else and im so confused!!!!
