It sounds like you’ve already done a great deal of recovery work. It must be discouraging to feel so stuck with terrifying memories. I do have a few suggestions:
First, I question whether talking about the abuse all the time is healthy for you. It keeps the bad memories front and center in your mind. I suggest you try focusing on and talking about something different for a few weeks to see what happens. There is research that people feel better when they spend the last few minutes of every day writing down at least 3 things they are grateful for. Those things can be big or small. If you can’t think of anything major, focus on how grateful you are to have running water or to have had lunch that day. Big things can include your good fortune to have your girlfriend and friends in your life as well as for other specific things that happen. Then talk about those things when you talk to your friends.
Second: Talk to your therapist about getting a second opinion. Even the best therapists sometimes run out of ideas. That doesn’t mean that there aren’t other good ideas out there. You may need to talk to another therapist or two or three. They will bring their own ideas to the situation.
Finally: If you were seeing me, I’d suggest that we try some hypnosis to see if that would be helpful. I would help you learn some self-hypnosis so that you would have another tool to help yourself. Do talk to your therapist about whether that is advisable in your case.
I wish you well.
