Can't seem to get myself help

I was raped by my roommate a little over a year ago and I started going to therapy after that, but quickly after starting I just stopped going. I still can't rationalize why I didn't keep going because it was starting to help. Now I can't even bring myself to make a normal doctor appointment let alone actually go to it. I just get so anxious and end up just sitting at home instead of going. I don't understand why I keep doing this.
