I've definitely gotten better at consciously adding things the list of shit I try not to to think about. Which is pretty long at this point.

I finally tried weed well into my 30s and discovered it's great at making sure I don't think about those things when I'm trying to go to sleep, which is really nice.

In general I'm pretty sure I've got a fair amount of derealization going on all the time now, which... helps?

I suppose that all adds up to some kind of mellowing out.
