I've found therapeutic writing really helpful for me, it's helped me untangle why I feel shame or a lack of self-worth, and helped me to see that I feel subhuman, horrible, less than - when really the people who harmed me were the subhumans. It has helped me re-order and put things in their right place. It's been really helpful, I'm not so much tangled up in a twisted ball of shame and insecurity. I write for at least 20 minutes every couple of days. I used to do it every so often, but writing regularly has really helped. I like that it's simple and free too. I also do some compassion meditation (it's a Buddhist thing), that helps me respond to myself more kindly, and some CBT always helps :).
