I get paranoia too. I think it's part of my catastrophic thinking problem. Only recently I'm ready to face it, was too paranoid & superstitious to even mention it before. But it's a problem. If I'm calm enough I can talk myself through it, think it through rationally, challenge my beliefs. If I'm not in a good state, I hide in my room, cry, pace, panic.
I'm so sorry you're going through it.
The med might help. But benzo's you don't want to be on forever & docs could cut you off anytime... Or the gov could make them illegal. (Sorry that's prob extreme paranoid thinking right there :/ ).
Ideally, my goal, I will come to a calm place of peace where I understand that bad things are going to happen, they just do and it sucks. And I will somehow get through them. Look back on every hardship we have been through and we are still here.
It's like I hope to become a Zen master lol. Work in progress.
