School stress😭

I had to go to dance today for 2 and a half hours then come home take a shower and eat which took like and hour then I had to do my biology homework which took two hours! And I'm not even done, I was only on page five of the 26 pages to read (took me a long time because I had to take a lot of notes and find answers to questions my teacher gave us) so I finally gave up and said I'm going to go to sleep. So what I'm gonna get an F probably but it's the second week of school and I'm this stressed. It's unhealthy and I can't even sleep.
