Just out of curiosity what meds are you taking and how much....maybe you could use an adjustment? I think it's super hard to fight delusions just with reality testing...there are often small things that make you believe it's true that aren't even rational to another person. Like I just knew everyone with sunglasses or their window rolled halfway was trying to recruit me into their organization.......there was no logic testing this. If it helps you can make a pie chart with all the logical and illogical reasons for why this is happening...I learned this in cbt. You put down all the possibilities and assign a percentage to them. It's not so much that you won't think there is a 75% or higher chance the delusion is true but that you'll find there is a 1-25% chance it's not true......
