Exhausted😴😴😴

I wake up at 6 every morning for school. I got around the same amount of sleep I always get. I'm not on my period so that can't be why I'm so tired. I go to school get out at 12:20 and after I have another two hour class that gets out at 3:30. I have so much homework it's not even funny😩 I came home and slept because that's how tired I was and now I feel the exact same. Really don't want to drink coffee because I have to drink A LOT to feel something and then my stomach starts to hurt and I really don't like energy drinks. But I need to get energy somehow to write a full essay, study for a test, and do math that will take me at least two hours alone. Does anybody know what I can do?
