I think this goes deeper than make-up... I was a tomboy until age 15, as a little girl my goal was to be more manly than the boys I played with, and now I'm as feminine as they come and I DON'T wear make-up.
Tried it, and decided I was pretty either way,so why bother? Besides, it speeds up the ageing process...
What ignited this feeling? Was someone mean to you? Was something said in a conversation that sparked this feeling? Is it boy-related?
Each one of us is work of art. God doesn't make mistakes... Wish you could learn to love yourself, that's my current mission in life.
