An underrated aspect of depression is that, if you have good days and bad days, your bad days just eat into your good days. Like you just generate this labor deficit for yourself and end up spending your "good" productive time doing dishes and cleaning up after yourself. For people who have their depression in a manageable place, that's something you deal with. But for people just getting out of a deep depression it highlights how many different layers of support you really need to get there.
