Hello shymitt, I too know those conditions. I've known a long time I've thought myself worthless, and it's only been about a year that some small change has started. I have found it in therapy only. My therapist is sexual trauma trained, and is very aware of nuance in living and conditions.
It took me a while to find her, and I tried a man at first. He was in my network, she is too, but 2nd tier. There are a lot of things that went on for me to find her.
I researched some few Psychologists and trauma pretty well. I learned what I was going through, before and now with my therapist. That education has helped me greatly, I'm very receptive to what works for me now. I had a very big chip on my shoulder prior to this therapist. I didn't believe therapy did anything for me, nor thought it really helped anyone, I've changed my mind.
I have had EMDR and Sensorimotor therapies, and then Cognitive Behavioral with them. I know some others discuss theirs around the forum, and I do a lot of sharing about therapy. Responses and sharing has helped me understand what I'm going through with these therapies. EMDR and Sensorimotor especially. They're not easy to get started with in my opinion, I found the research and preparation to be extensive. Now it's worth it.
I have gained the knowledge of what parts are, and that's way to hard to explain in a short post. Those parts are helping me the most, and it's done with the EMDR and Sensorimotor, and CBT to sort out my thinking. I get confused as I interact with my parts. Essentially my parts are each age of me, the inner boys, that I interact to establish their trauma (mine) and what I as the adult of us is trying to do to help make progress. The goal to me is manageable. I want to live life and stop hiding. Stop fearing and being anxious about so much. Then, the miracle of liking me seems to be there. I have a small flicker of it, a dim star in the dark sky, and I keep hoping to see it glow. So, I keep up the work with that hope.
Best wishes, and welcome to this caring group.
