I'm always tired and wanna sleep, ill come home from school and fall asleep and then be awake for like 2 hours and go back to bed around 10-12 and still be tired (wake up at 7: 20am) and it's been like that for like 4 days and i'm still tired. maybe because been feeling a little down?

I think it's because the person hasn't been getting sleep and doesn't know how to stay asleep and just wide wake and stays up. So their health isn't going to get better because  of their sleeping problem.

1.)dr. natterson- horowitz came to realize that their isn't much of a difference between animals and humans. just like humans, animals can suffer from illnesses and diseases like breast cancer, self injury, anxiety, and many more. she also discovered how they even treated and performed surgical procedures on animals just as if the animal it self were human. the los angeles zoo called dr. natterson- horowitz because they knew that she was a doctor and that  she would be able to recognize what was wrong with the gorilla. they knew that humans and gorillas were similar, so instead of calling another veterinarian, they called a doctor.

This is true! hope this : ))
