Have you tried actively and aggressively challenging those thoughts?

Obviously you have no way of knowing what anyone else thinks, so I'm a bit curious as to how exactly your mind is able to run so rampant based on zero factual data and how it manages to triumph over your rationality every single time...

Sounds more paranoid as opposed to anxious, but then again I'm no doctor, its just my opinion.

Whatever it is, it sounds horrid, not just because I'm pedantic about implementing logic, but because that must be really lonely...

I'm sorry you're struggling with such intrusive thoughts and hope you find a way to battle them effectively.
