Occasionally once every couple months I'll have break down level paranoia where I believe even family and friends have a plot to kill me. It's not often but it's scary when it does happen. I used to abuse heavy stimulants, so I'm wondering if this is residual stimulant psychosis, ptsd, or bipolar with paranoia (I've had that thrown at me)
Stinulant Psychosis is traumatizing in my experience. Once the trauma gets triggered, it can throw you right back in that headspace.
I use a combination of IFS (a type of therapy) and beta blockers to work with my CPTSD, and no longer have full blown psychotic episodes unless I'm exhausted. Some of my trauma does come from stimulant abuse when I was younger.
