Could this be PTSD? Should I see a doctor?

Hey,

I was in a relationship that lasted two weeks and I've completely forgotten about it. I thought it was because of the drugs (I was taking them almost every day at the time). I'm just surprised that I remember the time before that, when I was taking just as much, so much better. Slowly but surely a few memories are coming back, often in dreams or through photos in my gallery that I don't even know about. I've forgotten a lot but I know that she hit me, she threatened to kill herself and then locked herself in her beard with a knife and hurt herself, she was often at my door after we broke up, she deliberately filled me with alcohol and benzos so we could have sex, film it and then blackmail me, and she secretly searched my phone. Unfortunately I don't know anything more at the moment, should I check with my doctor about it?
