Gangstalking

Therapy maybe?

realistically: probably see a psychiatrist, work with them to figure out an accurate diagnosis, may involve treatment like anti-psychotic medications

I actually had a similar problem. In my case, though, I just asked the leaders of my neighborhood‘s local gangs if they could please have their conversations somewhere else. Luckily for me, they were cool and seemed to understand, but I guess YMMV

Sort of a case-by-case thing but questions like this have led to productive discussions between me and my therapist. Hard to say more than that from where I'm sitting though, we all respond differently to different things.
