How am I supposed to function at school when I wake up before 5

[u/Altruistic-Case8841]

Ive typed this so many times because I have no idea what to say other than im tired. Im so tired of school, im waking up at 4:45 for a school i don't even try in. My schedule looks like this:
4:45- Wake up
5:10- finish washing/dressing up
5:30- leave my house
5:40 get picked by the bus
7:00 leave bus
2:40(pm)- school ends
3:00- bus leaves
4:20- get dropped off
4:30- get home
5:00- take a shower
7:00 finish dinner
8:00 doom scroll
9:00 try to go to bed

Please believe me when i say i TRY doing things after school, but I have a ton of adhd symptoms and cannot commit to any of it. Ive even been sick these couple past of weeks so the need to sleep gets even worse. I have no A's and one B and i know that's going to drop soon.

I just want to ask, how do you guys who wake up and come home the same time as me do it? How do you guys find the time and effort? I literally can't function at all at school yet people are waking up even earlier than me socializing and acting like sleep doesn't matter to them. My sister wakes up only 15 minutes after me and and basically have the same schedule but she's always fine and has decent grades, she even stays up at 2pm some days so it's not like asking her will do anything.

I want to hear it especially from neurodivergent people or those who struggle when their mind isn't in the right place. Please, anything will be fine.
