As per PeelerSheila - sort the problem. My prioritised list would be - kitchen (including washing up and countertops but not floors), bathroom, bedroom then living room. In short, do small bits with big impact, then work down through the list. The floors can wait, the washing up can’t due to microbiology. A big area like the living room - find a dump zone (eg tabletop/sofa), then put all clutter there. Then straighten up the furniture (and floor if you have the energy) then depopulate the dump zone item by item into its proper place. There’s a hundred ways to do this - it’s finding one that’s doable for you right now.
