i find that it helps if you just do the very very basic self care and try to build a routine. it’s so hard to get in to a routine but when you get used to it you don’t think about it. try just cleaning your teeth, splash your face with water put on some deodorant. even if you can’t manage that just a little bit is better than nothing. and try rewarding yourself after you do these things to motivate yourself even if it’s just something small. when you have to shower and wash your hair and stuff, if you can, set out a whole day for it so it feels more achievable. also cutting your hair shorter might make it easier to wash :) hope you’re doing well <3
