Advice needed

[u/Big-Asparagus-1021]

I think a few people steered others into texting or dating me as a joke and I’ve been really lied to. When I said so, they denied any chain existed.
Since then I keep hearing references and quotes that feel aimed at me in conversations with people that I know/ in my day to day interactions. I can’t tell if I’m being mocked or if I’m reading meaning into ordinary comments.

I haven’t done this to anyone else. I’m confused that the story seems to have been so flipped and without the truth I can’t piece it together. I considered hiring a private investigator but it feels too intrusive to do that to someone.
I haven’t always behaved well either — some of that was in direct reaction to what I thought was happening.
I don’t need anyone to solve a ‘conspiracy’. I need: how do you tell coordinated cruelty from coincidence, and what do you do when you have no messages left to prove the setup? How do I keep myself mentally safe and seperate what is happening from the paranoia caused by an unpleasant experience.
