Bless your heart! I'm with Shezbut in that I think your T was way out of line with her remarks. Even if she DIDN'T know you were insecure about your looks, those remarks were uncalled for. That would hurt anyones' feelings! And when you're insecure besides, it knocks you for a loop!
I also agree that you need to talk with your T and tell her how these remarks were hurtful so that she'll know that further remarks of these kind will hurt. She should know about your insecurity about your looks -- and besides she should understand that those kinds of remarks should NOT be said to anyone! She must be an idiot to think that people aren't hurt by insults like this. So please talk to her. She needs to be "put in her place" so to speak.
I'm sorry you had to go thru that. It was totally uncalled for. My thoughts & prayers are with you sweetie. Please take care of yourself. God bless. Hugs, Lee
