I have a sort of chronic pain, sometimes there are very intensive periods and sometimes it become less intensive but its still there. I've experienced a long period of intensive pain once that lasted for years.
My distractions are: Sleeping, food and drinks, anything related to sexuality like sexual thoughts, playing games, listening to music, watching anime, previously I went to gym and it was a distraction but never a solution.
my pain is one of the reasons but its not the only or main one. I've got a more complicated state and whenever I'm less pained I get anhedonic and its very ugly that I wish the pain comes again. Also not to mention the countless shitty stuff from life. All of these stuff get mixed together and form the reason for CTB.
