First,I'm gonna tell you some info to understand this text better.

Grade system in my school is:

5-excellent (best grade) or

4-very good

3-good (middle grade)

2-enough (grade you get when you are really bad,but not fail,something like a gift haha)

1-insufficient (fail,worst grade)

Okay,so this is my problem:

I think my teacher is being disrespectful to me.I have selective mutism,so that means I don't talk to strangers or teachers only to closest people and family.She acts like I do it on purpose,like I'm rude or something.She gave me 1 (look at the grade chart) today because I didn't tell her to bring a paper sheet for my classmates (some kind of tasks).And how could I even tell her,I can't talk to her!Other teachers are kind,they understand and they support me to do my best (I write them notes when I need something).But not my math teacher.Everytime when I need to tell something,which I can't tell actually,she looks at me like I'm some kind of a rude girl,and punishes me.When I smile,she says to me like,why are you bothering the rest of the class,gives me 1,and says that I can talk to everyone else,but her.BUT I DIDN'T DO ANYTHING!She isn't fair,it's not my fault I have SM.How can I talk with someone,when I just can't because my brain has disorder.Please,what can I do about it?I can't take this anymore,I almost fail math every year because of her,she gives me 2,but says that I'm being very very rude not talking to anyone.Please help me.
