FWIW, I have kept an Excel budget spreadsheet since at least 2012, lol. It is the only way I can feel sane about money management and assured I am remembering to pay all my bills on time.
I'm trying to get in to keeping up with stuff like that and when I lived on my own paying rent that's exactly what I did. Probably because the other options would have destroyed me. Moving out again in a year and I'll likely figure something out. For now it's trying to organize my day though as I'm taking online courses and it's very difficult to stay on top of things. Actually just finished planning out tomorrow including a block of time devoted to "free time". I'm realizing that if I want to function in society I need a schedule and next step is the budget stuff.
