How to tell if i am having paranoid delusions?

Hard to do alone: If there is someone you trust, lay person or pro, try to ask them to confirm or challenge your point of view. Let them know that your idea is what you believe, but that you have a doubt. Just asking this here is a good sign that you might find relief but it takes a helper. Depending on things unstated, you may even be able to do it without drugs. But they might be needed too. I'm hopeful for you.
