My teacher is being very mean to me plz help!!!?

I see this question from both perspectives, yours and that of your teachers. I am a teacher. It sounds to me as if your teacher is a bit strict and a bit burned out. I have kicked students out of cl, but it was for blatant disrespect and I give them 3 times to shape up or ship out and it is usually not for not working but for very loud disruptive behavior. If I think a student is sick, I usually ask them what the problem is and then I say just see what you can do and let me know if you continue to feel bad and I'll send you to the nurse. Or I say I'm sorry you don't feel well, how about you rest now and we will work on it together at recess or you can just try to finish your work despite not feeling well. I would never throw anything at a student and I would never say what is wrong with you. I am the one who sets the example and that is to be a positive and encouraging and empathetic role model. When a student doesn't want to do their work, I do my best to motivate them, because that is my job. So, ask yourself, were you being lazy or were you legitimately sick? The teacher did wrong, but did you provoke that teacher to become frustrated with you? I have no idea if this is the case, because I was not there. If you feel you were treated unfairly you can talk to the principal or your parent and this teacher will be spoken to about how she runs her clroom. Respect works both ways. Students need to respect their teachers and teachers need to respect their students too.
