First: I hope your back to the better improve you soon. I suffer from Chronic pain from too many years of living and I know on painful days everything is always looking worse than it really is on a good day.
Second: You have some clutter, not a pig sty. For that you need a shovel at the door to shovel your way in and out. You just have to look hard for things than some.
Third: Craftybear is right some totes under tables with a tablecloth solves oddles of problems and even mounted shelves on the wall on metal brackets would be an inexpensive way to solve storage clutter. All this can be done on a monthly wall project. Start first with the totes, tablecloth then the shelves.
I hope this and a I UNDERSTAND HUG will help. One day at a time fixes m any things. :D :D :D
