I forgot to cancel a 1-week free trial of a stupid PDF software I needed to use once in an emergency, and I'm now out over a hundred dollars because of their subscription fee. 

After 2 weeks of dealing with Google Play support, emailing the developer and contesting the charge with my credit card, I now somehow have to accept I have given up over a hundred dollars for a stupid software that doesn't even work well. I can't stop ruminating on this and it's probably ruined multiple days of what would otherwise be a good week. Being able to quantify how badly I messed up, and how wastefully (I could have fed 25 people or offset my carbon use for the year with that money, and instead it's basically been lit on fire) when I lose things or money honestly takes me to the edge of self harm. I know eventually I'll accept this but it might take me months or years as it has with past financial mistakes.
