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)
Good luck, comrade. From personal experience, it gets better. Try to be kind to yourself as you unpack it all.
