Any extremely low-effort suggestions?

Hi, I'm in the throes of severe depression at the moment. I am on a lot of medication and have had to give up work. Struggling massively with fatigue and total lack of desire to do anything - my days pretty much consist of sleep and staring into space. Baby steps like taking myself for a short walk, trying to read a page of a book, putting on a tv show or having a shower are a monumental battle that I usually don't win.

Does anyone have any suggestions for self care that are incredibly incredibly tiny?

My thought is that maybe if I can manage some extremely tiny things, I might be able to work up to the bigger (though still small) stuff.

Edit: Wow, thank you all so much for your kind words and ideas - I don't think I can express quite how grateful I am.
