I need someone to tell me i’m going to be okay

I’m stuck in a very emotionally and verbally abusive home nobody wants me here but i no longer have anywhere else to go. i don’t have a room in my own home so i live on the couch. limited food, absolutely nothing to drink, i’m not able to afford anything for myself because i don’t have a job but it’s looking like i need to get one. i’m 17. my boyfriend of two years broke up with me out of no where, i’m pretty sure my mother had something to do with it. he was my everything, he took me in and took care of me for two years when my own family didn’t give a shit. his mother showed me what it’s like to feel real love from a mom. now i’m all alone and i don’t know what to do i’m so emotionally drained and i just want to scream.
