I accidentally triggered myself...

I went through my backup photos to delete some that were just irrelevant and work related. Sure enough, just like that it put me into an episode after seeing some that were personal and I became overwhelmed with grief and regret. I rode out the brunt of it, but here we are the day after and I'm coming to the tail end of it where I feel like crap. I'm doing everything I can without Paxil meds, until I'm able to get insured and all. I found cold water puts me into a moment of shock, and helps get me out of it...and unfortunately pain stimulation for the same reasons and to release any energy. I went out of my way to get those "little ouchies" you see on TikTok to squeeze the hell out of versus punching or anything.
I'm also planning on getting more active and looking forward to biking trails.
But aside from these things, is there anything else I should be doing that would help with PTSD episodes?
Shaking doesn't do anything for me really. Nor counting and breathing when I'm in the heat of it. Anything that kinda just "shocks" me helps.
