I have also realized I suffer from PTSD. My triggers involve feeling overwhelmed in general, being around my dad, making plans for my future, and sometimes just stimulation in general (living in the city, I get a lot of it). Unfortunately there isn't a magic answer. It just takes time, patience, effort, and a sense of gentle curiosity with yourself and the things you learn within and without. I'm currently somewhere in the middle of it all, though I'm having a depressive episode at the moment...
I'd like to know how you're doing now, if anything's progressed or improved for you or if you have had any new insights that have helped you in your journey.
