@hazlin I am a schizo in that I unironically believe that bad events will happen unless I think about them. I know that sounds retarded but Ive accumulated enough anecdotal evidence that I can't shake the feeling. This has pretty much resulted in me being the ultimate pessimist.
However, if there is genuinely nothing at all I can do about an event, I write it down in a log of "bad shit I can't do anything about and the date it will probably effect me". It does nothing to make the situation any better, but it makes the worries into a concrete list rather than having a backlog of vague nebulous things I'm in fear of and I can't remember what they are.
