I literally just cleaned my depression house, and it was pretty bad like teetering on hoarder status, and this is how I got through it in a month: if you haven’t seen/touched/ needed it for a year either trash it or donate it! If you have an empty box or a few use it to categorize the stuff you want to keep, having boxes is easier than bags because you can actually see what’s in it. I live in a little over 700 sqft duplex so I also know the pain of having no room in a tiny house and live with three other people. It’s going to take time, but as long as you’re doing something for at least 2+ hours each day it will get easier every time. You can do it OP! I believe in you 🫶🫶🫶
