Seeking help

I’m 21 years old. Was dating this guy i met in 6th grade when i was a senior in high school. I broke up with him because he would leave me hanging for 4 -7 days no call no text. We got in contact again 5months later and we dated again. I moved in with him & for 2 years it was constant abuse. He would hit me in front of his little sister & brother. I would bleed from my face and hands. I was too scared to leave him because everytime i tried he would hit me worse and lock me in. I left him 6 months ago when he got a new job that consisted of him not being home. Today i struggle with really bad anxiety and severe depression. I get flashbacks at work and i cry hysterically. I know i need help but I’m too scared. My last dr visit my dr asked me what gives me anxiety and depression and i cried so much when he asked me if I’ve been hurt. He diagnosed me with PTSD. Don’t know what to do. I feel like hurting myself and ending things with my life. I just cant talk about it it hurts
