Do you guys take care of your appearance?

After I graduated high school, I became a NEET and completely isolated myself from everyone. I gained a lot of weight, became insecure, and just really didn’t take care of myself. After 3 years, I got sudden motivation to fix myself up and started to workout. I lost weight, started skincare, makeup, doing my hair, and overall just dressing/looking presentable. Despite doing all of that for some years now, I question why I bother when I have no reason and nothing to look forward to. I have 0 friends or acquaintances and I don’t go out at all. I could try but I have horrible social skills (social anxiety) and I’m very timid so I’ve just completely given up on that. I know I should do it for myself and no one else but sometimes I wonder why I bother. I know being a NEET comes with some stereotypes of letting yourself go and not taking care of yourself so I was just wondering of other people’s experiences and if they can relate.
