I'm sorry I can't make this any bigger but here is the LINK so you can go there yourself and read up about Complex Post Traumatic Disorder -CPTSD and BPD -Borderline Personality Disorder.
If your therapist isn't correctly diagnosing your condition how can they treat you correctly. We cannot sit back and wait for miracles, we have to do our own research to find the solutions we are so desperately searching for. In my own case once I was diagnosed with CPTSD, my therapy went into a whole new direction and healing came slowly but progressively over time. Can we heal? Yes absolutely.
