i’m getting worse

This is just a little background story, last year in April 2019 I couldn’t go home for at least a month because of an abusive situation at home. I did a lot of house hopping but the main place I stayed was at Amelia’s house. The entire month I was extremely sad, always stressed out because I never saw my mom. During that time I started drinking and smoking a lot, almost every day. I had a boyfriend and every time he would see me I was drunk or high. It got to the point where my friends started to get concerned and almost contacted my sister about it.

Fast forward to February 1, 2020 my biological dad who physically attacked me messaged me for the first time in 5 months. He said he did nothing wrong and I was overreacting. Now i’m drinking a lot again, It’s my 3rd day drinking in a row and it’s just to distract myself from everything that happened.. idk what to do.
