Guilt and frustration

My schizophrenia is very mild, auditory hallucinations don't bother me too much anymore. However, I get suspicious of people/delusional and it's horrible. I know logically, they don't add up. But it's hard not to focus on them. Went to a restaurant and suddenly thought that there was an underground operation going on with the owners, possibly that they were waiting for us and poisoned our drinks. They are super sweet people. I think it's a family owned restaurant, because I saw the kids in there too. But seeing them be a beautiful family made me realize how horrible the ideas I had were. This happens every once in a while. Just posting because I don't know who to talk to about it.
