Hello Diana,
I know what you are talking about, mainly because I compare myself to people from school and wish I looked and act like them,but i’ve learned to accept who I am and love who I am. Yes I have a very low self-esteem at times but I get back up again just like you. I think you should think positively about yourself and not compare or think you’re any less then that woman you work with. You’re beautiful inside out and can do anything.
I hope this helped a bit or gave you motivation.
Celine.
