if I'm delusional I fully believe them as absolute truth
but I can also become deeply paranoid when I know more than likely it's not true but the fear and thoughts are there anyway.
if you can get a hold of the paranoia before it turns to full fledged delusions then that is your best bet.
Im not sure how to do that besides trying to ground yourself and talk to someone and don t be alone
there are many wise ppl on this forum that will have better advice
but know I'm feeling for ya
