Jennifer you have been through so much this last year! I hope that you have a good T, someone who is experienced working with PTSD/trauma, stress, and chronic pain etc....it will make a world of difference in understanding and handling, and healing.
I think the trauma may very well have set your system off with the stress chemicals... perhaps they never stopped firing from the trauma? PTSD makes the body run on fight or flight all the time, and that can truly upset the whole system.
Thanks for the update, good to see you back at PC, hope things begin to smooth for you soon.
