So I've learned recently that apparently a lot of us may become delusional when stressed. I know not everyone experiences this but I'm wondering if I struggle with it. I just don't want to say I do if I don't. However sometimes when I'm stressed out I start believing things that have no evidence for them and I can't shake them off. The most common one is that my boyfriend is cheating on me with a particular friend of his. Every so often I'll question him about it and he'll tell me that he's absolutely not cheating on me, he's a pretty trustworthy guy. But its like it doesn't even matter to me in those moments. I have violent thoughts (which I would not act on), I become incredibly upset and anxious because I'm convinced of this belief. Is this delusional behavior? Like I said nothing can shake this off and I'm scared of acting this way again.
