i keep getting stuck on different causes that trigger my unwanted thoughts even though they have nothing to do with one another. for example, there's this lie i told to my mom about two years ago that i wasn't skipping class. i was written up for it, but i told her i didn't do it, but the truth is, the whole time i was hiding to avoid taking a test i knew i'd fail. now i'm telling myself that i can't stop thinking my unwanted thoughts until i tell the truth for that lie. i know it's counterproductive, but does anyone else have this problem. what do i do about it?
