Hi SuperiorOutlook,
sounds like you are struggling a lot . PTSD is complex and while this board provides a supportive and validating environment it can't cover all aspects and in some ways could be even triggering as it provides plenty of reminders of what happened.
I suggest you spend some time researching and understanding your options as a first step. I found the
The Post-Traumatic Stress Disorder Sourcebook - Glenn R. Schiraldi, Ph.D. useful both in short run explaining the mechanisms behind the symptoms and immediate self care measures providing relief as well as in the long run looking at the various therapy options. Eventually you have to find and discuss with a professional T how to move forward.
I used to be such a sweet, empathetic person with a great sense of humor and now I feel like an enigma, it makes me so sad.
It takes a while but realizing what you are dealing with and taking targeted steps will make you feel better and more whole. PTSD is a situation where coping mechanisms are overloaded and misdirect us. The sooner it gets handled the less dysfunction has built up so don't hesitate to reach out for professional help - disassociations, curling up are symptoms on a level that justify taking the help of professional guidance.
