Hi mistykelly and Welcome.

I can imagine it is hard for all of you to understand.

Was wondering, is your brother in any kind of therapy? I struggle with paranoid disorder (I sure don't like that title )--although not been diagnosed as delusional. Anyway, I have found so far... the very best thing has been when people DON'T deny my thoughts. It's so invalidating to be told the way one is thinking is WRONG or nonsense.

My current therapist has been very helpful in listening to me and then having me hear a different view than my own.... that has been a big help. I feel like I'm being listened to and also I'm given another possible view to think about. Not sure if it will help your brother-- but it is gradually opening my eyes to other worlds-- less threatening ones.

However, I believe that the person must really want to get beyond how they are currently functioning-- otherwise-- it could become a battle. Years ago-- no one could tell me there was anything wrong with the way I thought. I --myself-- got tired of the circle my life kept going around in. I hope your brother will be open to getting help.

I know of some websites I could steer you to if you're interested--- if so, PM me and I will be glad to send them to you.
Good luck to you, your brother and the rest of your family.
