I also agree. It is worth bringing up these issues with your T with a way and pace that suits you. You are right to wonder if traumatic memories are best left alone. Only some people respond positively to working through trauma directly. For a few it can be like a Pandora's box. One small opening and the whole past comes flooding out, overwhelming the person. For me it helped to talk around the issue of my trauma. The insight I have been given is helping me grow and heal. However, the couple of times I tried to go deeper the floodgates opened and drowned me. Everyone responds differently. Just bringing up a few of the issues you mentioned may really help you connect more with your T and make progress in different areas of your life. It's worth a try before abandoning therapy altogether.
