help me

Hi everyone so a while ago I posted how I was sexuallyassaulted by a guy who I'm best friends with and I'm now pregnant and I want an abortion but I don't know what to do I was raped and he told me I was asking for it I need help because I don't know what to do I'm 17 and he's 18 
UPDATE
Both of my parents are dead and my grandmothers crazy I am all alone I have no help (not an only child but he's away in China playing hockey) my brother is no help and we don't talk ever
