I'm struggling, too. Reading your story helped me feel less alone. So, you connected with me and I thank you. I am sending you prayers!!
I've just come across Anna Runkle (The Crappy Childhood Fairy), she has a book and talks about abuse, trauma, neglect and PTSD and C-PTSD. She also has videos on YouTube.
Also, what is really helping me now is doing EFT Tapping on myself. In thie video below, it teaches you how to do it. PESI Inc, that put out that video, has other helpful videos on YouTube, as well.
