I regularly don't shower for about two weeks right now. If I need too I can force myself for a special occasion but it's usually 2 weeks right now. I've never been a big perspirer. During the pandemic I didn't wash for months and I DID Smell. Also my hair was matted. That was at also at a time I quit smoking and drinking. It was bad.
At the moment if I can't get in the shower then I just wash my private parts with antibacterial soap. Sorry to be graphic but I'm just being real. Before people manage to find the tools to get better and improve their situation it's normal for things to be bad.
I used to hate myself. I was really f*cked. But now after help and self help I love myself as much as I can, and others also. I hope that you can find ways to love yourself aswell.
And that feeling of getting out of the shower and putting on clean clothes is wonderful
