I am about to undergo therapy (from Monday) for issues relating to childhood psychological/emotional abuse, neglect and sexual abuse. I've a history of self-harm, my GP had proactively diagnosed with PTSD and CPTSD, backed up by a counsellor so formal dx should be incoming.
I though it might be helpful for people to understand this journey, and I'll happily answer questions.
