How should i end it with him?

i am slowly becoming more and more depressed. I have a boyfriend for about a year and i only have a mom. but i still am constantly upset, my boyfriend gets to go to sleepovers, stay out late, party, have friends. i have none of that. i feel that if i stay with him longer it'll get worse because he has it off so much better than me. i dont know what i should do. he cant help and says so himself. but hes the only one who actually cares because i have little to no friends and i dont even know my family. so how should i get help? or should i break up with. but if i were to break up. i would have nothing to do all day. and might as well end up killing my self.
