I'm in high school, and I was absent today. A friend of mine was my partner for an art project, and my teacher saw he was working alone. She then proceeded to scream in front of the entire class: "You should find a new partner, because *insert my name here* is always out because of her disease." I'm rarely ever absent because of this. I am very hurt by her comment. Is there any action I can take? Is this discrimination? Please give some advice!
