I donated all of my things except large furniture, and gifted some things to a friend who is aware and understanding. I rehomed my pets to an excellent rescue who keeps me updated on their health (one of my girls was adopted!), and ensured I set them up for the best life possible by buying their essentials in the highest quality I could.
No official will (just a written info dictating body disposal / personal request (listed below)) required because I am living alone and nobody I want to give anything to. So anyone can have my stuff leftover. I threw away most personal artifacts and left nothing except things personal to immediate family in a small box, like birthday cards and notes I've received throughout the years since I was young. Some pictures. Everything is sorted there.
I deleted and privatized all socials. I created an email to leave a will behind, pretty much just a brief explanation of why I'm leaving, instructions for no funeral/memorial, and to cremate me and my late pet and spread our ashes in a favorite forest of mine. I also included the login info for my credit cards and banking to make things easy. On that note I also compiled a folder filled with my government information, social, and any other potentially necessary documents as well as my cards (insurance, credit, debit, ID).
The only main data I have leftover retaining to personal life is my computer and phone. I've gone through and deleted some files and pictures from both but I'm unsure about deleting more right now. For some reason I have a hard time with the idea of wiping my laptop and phone. It's the last real things remaining of me here, and I feel heartbreak when I think of erasing this part of my life while I still exist. So I will leave directions behind on a note to wipe my computer and phone and hope that wish is respected. This is causing me a little bit of anxiety so I should prioritize addressing this soon and finalize the last couple of things.
