>is it possible for loneliness and prolonged social isolation to cause psychotic symptoms? am i losing my mind?
yes to both, humans are inherently social creatures despite our attempts to tell ourselves otherwise. If you have a friend you can confide in, I would suggest talking to them at least a little bit (it could be about anything, even an online friend could suffice). I'd also suggest maybe going for a walk outside or changing your surrounding for a bit so you aren't caught up in the subtle monotony that can drive yourself insane when isolate. Even something as simple as cleaning your room or changing the curtains can go a long way.
As for the feeling of being stalked, I've been there and the best thing you can do is to repeat to yourself "its not true" and reminder yourself that you are but one person in a sea of a billion of people. While it may be true that some data firm is collecting your voting records, nobody truly cares to constantly record and track you. If that were the case, many petty criminals especially cyber criminals would be caught by now, there would constantly be a social worker at your doorstep at any given time, and society would have cameras watching us in the home (and no amazon and google products people willing put in their homes doesn't count, i'm talking legit gov Orwellian shit). The truth of the matter is that not only is that shit massively expensive and impractical for a gov (I've worked in gov, I know trust me) but its also a violation of privacy laws (which despite gov repeatedly trying to break with shit like the Patriot act and Prism, it always comes back to bite them in the ass and still many things slip under the radar because of the impracticality of it all). You aren't being watched, except for cookies on sites designed to advertise you useless shit and chances are you already most of that blocked with browser extensions. Just don't go on shady sites and align with shady people and you should be good.
It might be worth it to tell your psychiatrist about these delusions. At worst you could be schizophrenic, at best you could just be very autistic. I'm not a therapist or a psych medicine person though, I'm just an anon with too much free time.
