My own therapist (had a difficult childhood, along the lines of you, OP but not as extreme by the sounds of it, which left me with complex PTSD) explained to me that moving on from trauma is like travelling through a conch shell- at first, you return to the same point in the “spiral” a lot, frequently, and it’s a narrow, uncomfortable and painful journey. Then you move on, and you find you come the “spiral” gets bigger- you come across reminders less, you’re triggered less often, you have more space. You’re more comfortable. You see light. If you keep going, one day, hopefully, you pop out of the bottom of the shell, free.
I hope you’re way along your own “conch shell” journey. I hope one day, you realise you can look behind you, and see your conch shell there, discarded and no longer holding you.
I think you sound like an amazing, strong woman. I wish you peace.
