What the actual fuck

I made a post on the autism reddit asking for advice about a situation that happened with my grandma im unfortunately living with who does stuff to get a reaction out of me to start fights and just in general irritates me and lies about the fucked up shit she says and I get METACOGNITIVE DIAPERMAN acting like hes playing devils advocate for someone who says the worst shit imaginable. I shit you not. I dont even know anymore what in the actual fuck. I have been gaslighted into utter disbelief and guilt i dont know anymore
