This I stupid I know....

I just asked my mom if I can stay home because im sick and not with the flu.(ps she knows that I don't have the flu). And she denied my request saying I'm not sick enough to not go to school.
Now I know I'm being stuck up or dumb but it hurt me to know that my mom won't even let me stay one day at home because I'm sick and she knows it, I'm not saying shes a bad mom but it's really hard to stay happy in this house when small stuff like this happens. Now you can disagree in the comments if I'm wrong but I just need some comfort rn please
