If you are the kind of depressed that makes you tired all the time, unfocused and unable to plan, doing stuff IS hard. It's not being POSITIVE about sitting there and rot. But "just" cleaning is hard when depressed, it is hard to get your body moving, it is hard to plan, it is extra draining because it doesn't come natural anymore, you mess up easily because your mind is simply not in tune with what you are doing.

So is it bad to force some activity? NO. But if you manage while being tired and low, you need about a million pats on your back. Also, it the cleaning turns out OK, you can be happy about the result and maybe it will help a little. Maybe even inspire to keep going at the pace you are comfortable with.

But don't beat yourself down and think you are happy if all you can do is sit around. Only idiots would claim that.
