cellardoor,
I feel bad you lost your baby. I have lost 2. I after approx. 35 years still dream of the one I held in my hand. The only advise, I can give you is they say sometimes it is a way your body disposes of it due to major defects. I know when I was unaware of being pregnant, I drank alot and do feel guilty till this day that it could have been me.
You need to help yourself by getting well through meds docs ect if necessary. I have had insomnia for many years and am now taking 3 different meds and finally getting a normal nights sleep. I wish you well, without sleep it is hard to function.
I do know in the U.S. one can try getting an attorney that if they feel you have a good case may take it w/o charge till you win. You most likely can use the PTSD diagnosis you recently received as a disability issue and with losing the baby it affected you much more than losing your job that you feel you were discriminated and unjustly terminated. One can still work and go with the disability issue.
