Struggling with Trauma Responses and Self-Blame

Over the past 6 months I have opened up about personal trauma that occurred in my marriage with my husband. We’ve done a lot of crying, and working on healing his past relationship trauma and my trauma as well. I believe I should feel joyous that after many years I can and have began healing, but I’ve been getting caught up in my own head, and emotions. I have moments where I know I am dissociated, and I can’t come back. So many things I thought were normal I am realizing were/are trauma responses. It’s a lot to take in at once…. I am also accompanied by immense feelings of guilt and shame about myself. I've made personal sacrifices I am ashamed of and I am also very angry at myself. I have such deep emotional/stressful pain inside me, I'm afraid to let it be known, it feels selfish. I am not sure what I am asking here but needed to get my thoughts out to someone who may understand.
