need wrds of encouragement/advice :'(

long post, but plz bear... my fam disapprove my SO and i of dating, but i still dated him. his fam has nothing good to say about him, suggested me not to date him, but i ignored it, and still dated him. ive surprislyn met ppl who knew him and they also suggest me not to b w him. i ignored and disregarded what everyone says. i was too in love & blinded. by the time of dating him, i was also on the path to my dreams/career dream. i was only 18 and already reaching them. the problem w my fam disapproving us went really bad, that i ended up running away, and married him. i then lost all my fam, my friends, my dreams. i cant go back to school anymore because i got suspended. i gave up my dreams to be what he wanted me to be, a sahm. i gave him what he always wanted, kids. i gave up my youthful yrs for him, i gave him my virginity. i did all this for him, in the end i get abused, physically, mentally, and emotionally. in the end it was a mistake to marry me, he regrets marrying me. im no better than his ex wife. im a useless piece of shit who means nothing to him. i get yelled at everyday like im a nobody. im just a kid to him, he cant believe he married a person who has no brain, whos stupid, and needs to die. who cant help do shit, i get called lazy everyday, yet when i want to go do something for myself and actually help w bills, i cant. he said if i were to leave him, he wouldnt care and regret it cause im no good. he makes me feel really worthless, ins4pjecure, not enough. been w him for 4yrs, i hate myself for giving everything up for him. i feel like a nobody. i cant find the courage to leave him at all. i dont understand why after all ive done for him, and he treats me like this?
