i have absolutely been there one way to help if you want it otherwise feel free to ignore   tell yourself you will wash one dish maybe just like one fork and then you can stop you might end up keep going because you realize its the pressure to clean thats putting you off rather than the cleaning itself or you might be every bit exhausted as you think and stop after the one dish its a win-win because your living space is cleaner even if it is just one dish its progress and make sure you keep your promise to yourself and actually allow yourself to stop after one dish or it will be harder to use this trick on yourself in the future  also not eating will hurt your mental health even more and i totally get not having the energy to cookeat especially when the kitchen is as messy as it is but you can buy those ensure shakes for kids to make sure youre at least getting some protein i hope this helps at least a little
