What kind of beliefs/delusions? If you don't want to talk about it I understand. If it's like, "Someone's going to kill me," that's PTSD or depression/anxiety related. It's not necessarily schizophrenic. Bipolar people can have psychotic symptoms on either end of the spectrum. They usually know they're hallucinating or believing illogical things. When you are convinced that they are true is when you have to worry (or other people have to worry for you).

If you know the thoughts aren't true, just tell yourself (at least this is what I do before and after a minor panic attack) these are only thoughts. I'm not bad or wrong for having them and I sure as hell don't have to act on them. Thoughts are often like dreams. They take minor fragments of thoughts, experience, and memories and jumble them all together as our brains rewire and restore themselves at night. Think of jumping sparks and wires crossing that have nothing to do with each other but are somehow linked in the moment of electricity.

If you do become too worried or obsessed by the thoughts and think you can't control reacting or acting on the urges, you do need to contact someone. But I'll be here to listen as long as I can keep up the fight.
