This is hard to talk about

I was in an abusive relationship for a year and half (sexual, mental, and physical). When the time came it was easy for me to leave. It took mutual tries but I successfully did it and left this past September of 2020. I didn’t go on a date for months. I was scared. I finally worked up the nerve. My friends set me up with this guy I like him. However I’m terrified. I had two people try to take advantage of me after the break up, I’m very vocal about how I feel. So, I knew I didn’t give them the wrong signal. Now, if sex comes close to happening I get anxiety and panic. He knows this. I finally told him. He said it’s okay and he would never ask me to do something I am not comfortable with. I just want to be back to normal. I’m 22 years old and I feel gross with myself. I think of all the bad things that had happened to me. So basically, I want to have sex again and not feel scared. I want to be comfortable with myself again and not be scared of dating. Has anyone been in this situation? How did you heal?
