My early 20's, I would say.
I am almost 50 and I will be honest and say that I haven't taken care of myself or my looks in years. I was a caregiver for my mom for several years and the last couple was her full time hands on caregiver, so I didn't get out much as I didn't trust anyone to "watch" her. It really aged me. Then my teen dd became pregnant soon after my mom passed and that was a kooky time. So now, is my time again,lol.
I used to get my nails(ok they were fake nails cause I bite mine), done, pedicure, waxing,etc. I am still losing weight(and I need to), so that is good.
I just don't feel pretty anymore and haven't for a long time. I will look in the mirror and sometimes see a glimpse of how I used to look.
