Yes, boredom and anxiety lead to confirmation bias. People try to fight belief attrition by seeking out confirmation for their existing beliefs and emotions. It's a thing. I do this by chronically coming here and consuming shit I already know over and over. It wont change anything about my life being shit, but it makes me feel better or justified on some level, even though I know it isnt. I look for reasons to be upset, justify my feelings of betrayal etc, when I dont even need to. It's a way of distracting myself from the sound of the cranky gate opening, as the reaper slowly comes down the garden path.
The thing is, as always, I am stuck. There are no options, no up or down. My health is declining and I have no social mobility, thus I am left to stew in my own juices 24/7. Hence, my thoughts are incoherent, disassociated. When I don't rot on here, I generate the necessary feelings in my head by daydreaming for hours. That's what I mean by riling myself up.
