SOME PLEASE help me i dont think i can do this??

so lately i have felt as if i am not wanted, my grandparents treat as if they hate me, and now the worst thing has happened i feel as if my boyfriend of almost a year doesnt love me anymore. I know he cares and he tells me he loves me and i can tell he does, but when hes mad or stressed he can be the biggest , he'll call me a b**** repeatedly. tell me im stupid and an idiot. and i hate it. it depresses me so much. i live with my gparents and my gma is in a nursing home part time and shes bossy as hell when she comes home every once in awhile.. and i do everything, cook, clean, laundry, call in bills, drive them places.. I am only 17 and i feel as if i am 40.. and have kids.. what should i do, someone plz give me advice
