I don't know the specifics of your trauma but I was mugged at gun point. I had to literally call out of work and hide all that day. I think I tried to sleep it away. Do whatever yiu feel you have to to just get the day over with.

on my trauma anniversary day, i try to plan something that i know i will look forward to, even if it is in the safety and comfort of my own home. such as saving a new episode of my fav tv show or podcast to listen to that day, open exciting packages that day, start a new art project or boom, etc. anything you know you'll enjoy
