Haters only hate because they can't be you.
Don't let it get to you, 1) its YOUR facebook.
2) You worked freaking hard so enjoy your new body!
Sometimes when we are unhappy with the way we look, we tend to have a negative outlook on other people's appearance or happiness.
I know when I was obese, I would look at skinny girls and say something mean, or insulting, or say she looks like a whore but now.
When I see someone with a nice body, I look up to them, I admire them.
It's all about how you feel on the inside. That's probably why it's hard for your aunt to see you that way.
Besides, you look hella hot on your avatar!! Work it girl!!
Ps. Since I've lost about 50lb, I've been posting pictures of myself in shorts, skirts, tank tops, I don't care. I worked hard for it and I want everyone to see it!!
Enjoy your tiny legs girl!
