Thanks teacup. Having been raised by the parents I have, I think I have a very high tolerance for pain. I think that's true of all the people on this thread: we are used to carrying emotional burdens and to keep soldiering on despite it. My miscarriage was very traumatic, physically and emotionally, and I think that because of that I just couldn't bear any more pain, which is why it precipitated my split from stbxh: even I wasn't able to tolerate his abuse anymore. My pain tolerance was maxed out.
The discovery about my parents shortly afterwards came as a surprise: I needed stability more than ever, and now my whole life was pulled out from under me; not just the 12 years of my relationship with stbxh. I've been plunged into depression since, and if I sound "wise and calm" then that gives me hope: it confirms that there is a solid bedrock inside me that will see me through this shit, and that I can build a new life on now.
Something's had to give while I focus all my energy on rebuilding myself, and it's my job. I love my job, and I have a very understanding boss. But I have been doing very little work during work hours, and a lot of mning and reading self-help stuff on abuse, assertiveness, CBT, and so on. I'm now at the stage where I feel I can let up the work on myself a bit, and focus on my paid job instead. I'm so happy about it: every week I'm a bit less of a wreck than I was the day before.
...but my god, the backlog of real-life responsibilities that has piled up while I was focusing on my psyche is huge and daunting...
