What should I do?

My daughter is being bullied at school. She is a very sensitive girl and socially awkward at times, and she is an easy target. It breaks my heart to see her fading before my eyes. She's such a bright and kind girl, but her classmates' cruel behavior towards her has been devastating. Because of the constant laughter and humiliation she faces, she’s now certain she is not like all the other kids. They made her think she is “weird” and ugly wearing her glasses. They tease and mock her just for fun. I worry that their verbal attacks will escalate into something more violent.

I've tried to follow the process suggested by the school. I've had a long conversation with her teacher about the bullying. It was frustrating and useless! I feel like my concerns are being dismissed. The teacher's suggesting that my daughter is overdramatizing and that she provokes other children. I simply can’t believe it! We’ve also been to a school counselor, my daughter visited him every Monday and Friday for a month. What’s the point of all this if her classmates keep calling her names, and the teachers do absolutely nothing? What’s the point of cameras and all those extra protection measures? I told her that she can stand up for herself and be mean to all those who tease her. She just can’t be mean. I told her to ignore them, for I know that children get bored and stop once there’s no reaction. But I see that it gets to her. Perhaps it’s my fault that I never prepared her for a constant fight.

She cries every other day when she gets home from school, and she got ill three times since the new year, which I can only believe is the result of this bullying. I really doubt she’s making things up. I just know that my daughter is not overreacting, and it's unfair for her to be made to feel that way. I’m at a loss for what to do to protect her. I feel helpless. Any advice is welcome.
