I can relate to this so much. I look like crap and have been wearing the same shirt for days. I will even go out in my pajama pants unless it's to a doctor appointment or something, and sometimes I even do that too.
showering is sporadic I go through periods where i'm pretty good at keeping up with it every couple of days but usually quite a few days will pass between showers.
the house is messy and I just don't care about any of it.
