No need for sorry.
Your posts are not upsetting, other than folks feeling empathy and wanting to help.
You really aren't alone, there are other members here with DID and C-PTSD. Some with only C-PTSD, some with both. I have both myself.
Let me encourage you that, as you work through the healing process, it WILL get better. At the time of the healing it feels like one will die it hurts so much, but you (and me) are strong and a survivor, and much more than surviving, you will eventually thrive.
Keep posting, you are welcome and cared for here.
