I'm glad you are finally starting to share a little bit of what is going on in your life and how you feel.
Just wanting to give you a word of moral support :) I'm sorry you had to experience that today. We've all been there to some degree, and it hurts, but as my mother-in-law always says, "No one can make you feel inferior unless you let them!" There's a lot of truth to that. Chin up. And remember:
"You are beautiful no matter what they say. Words can't get you down. You are beautiful in every single way." ~ christina aguelera
Go and have a listen to that song, Beautiful. It always makes me feel better :)
