Guys, help I am barely able to get through a day at school sometimes and my mom is really insistent about it.

i often have headaches along side ADHD and Autism and I can not handle school especially not five days straight. and my mom gets really upset about me not going for obvious reasons and i don’t think she understands how hard it is. i’m asking for emotional support and advice on how i can convince my mom to let me stay home.
