Oof well first things first, that’s definitely paranoia.Secondly, in terms of helping you, I can suggest things:-tell yourself you’re being irrational. that’s a tough thing but reminding yourself you’re being that way is actually a good grounding tactic-do distracting things at your peak of paranoia, such as watching TV, calling someone, playing games at loud volume, turn on a fan, listen to music. Even a combo of these things. Anything that distracts you and your senses and makes you feel you’re not alone in a dark and quiet room which is a paranoia nightmare-For the backstabbing thing, just keep your eyes and your mind open on them and learn the signs of when someone is trying to take advantage of you (gaslighting, being emotionally/mentally manipulative, making you feel bad or not respecting you, etc.), but also make sure you’re not overthinking things. Don’t be afraid to ask for reassurance from them if they’re rather close to you.-most paranormal things aren’t malevolent, despite all the spooky tales surrounding them. Search for nice and positive stories related to them so you can feel more at ease.
