How do you know if you have depression?

By losing interest in things you use to enjoy and wanted to do something bad. Not talking to people and blowing everybody off.

If you are in a constant state of sadness, and you don't feel like yourself anymore, or maybe you hate your life, or you've self-harmed, it's different for every person, to be honest.
I hope this is of help to you, and happy studying~!

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.
