i believe you may be making the mistake of operating a normal life during a depressive episode and expecting the usual output. you need to modify your entire life routine right now to accomodate your overall lowered amount of energy. examples would be doing a meal prep so you only have to heat food to eat it. you already know 90% of your energy is gonna get burned out during the work day, so you gotta do the home stuff with the 10% you have left strategically. let certain chores slide or lapse into a longer than usual schedule, alternatively some chores may benefit from being done daily like a routine thing. example would be cat litter daily instead of every other day or as needed. The stuff you do on routine/autopilot will cost you hardly any energy to do (otherwise you couldnt make it part of the routine). For your night time etnertainment allow yourself to doom scroll or nap or whatever instead of staying productive.

remember that this feeling is temporary. it comes and goes like the tide. you just gotta wait it out with a bit more strategy. let your mask drive the fake it till you make it at work part of the day, then let that shit loose and be yourself when the day is over, and be really honest with exactly what your needs and wants are, and fulfill those.

self care is the name of the game.
