Hello OP.
I'm a fellow childhood trauma survivor and have also tried therapy over the years, with varying degrees of success. To be fair, I'm not sure I was ready to face all my demons in the past. It's like each time I managed to chip away at the layers that had built up.
If I had the money today I would find an excellent therapist and buy workbooks, but I don't.
What has been helping me massively is watching Heidi Priebe on youtube. Watching her videos is guaranteed to provoke lightbulb moments for me, much more than when I tried therapy. They are informative, reassuring, soothing and, I find, offer practical advice. I come away from them with a better understanding of who I am, how I function, what's "normal", and how to get there.
I'm slowly getting in touch with the real me, building a true sense of self and can feel the benefits in all my relationships as I'm able to be more authentically me as opposed to playing a role/hiding behind a mask/doing what I think I should. It's very much a work in progress, but I finally, finally feel like I am making progress.
I can go at my own pace, watch and rewatch videos whenever I feel the need to. I'm also doing a lot of journalling. I'm finding it better than any therapy I've ever done.
I find that I come away from Crappy Childhood Fairy's videos feeling rubbish. Like she exposes the wound, turns the knife, then leaves me there bleeding.
Good luck, OP. Sending you love.
