I'm 5 years older than you and still haven't worked through the abuse I went through. I have tried a few times but it was either limited sessions or I didn't connect with the therapist. I know I still have a lot to work on.
I don't think it is resolution you need but you do need to open up and get it out. It will help in the long run. I have worked on some of it and now those things don't bother me as much. Your T will be able to connect the dots and do some work on how you feel about it now, and how that has shaped some of your behaviours. I had a really good T who helped me so much in such a short time, just 20 sessions. If you can open up to your T more, you might find that you start to feel better about it.
