Many people wonder " what is life," and to be honest their more answers than one answer.
Some some life is full of suffering, death, depression, learning, smiling and so much more. To be honest life is just what you make it.
before you say what about if you have depression?
well it not that simple to explain that one, but if you do have depression their are ways to help it, and some people just won't accept the help.
While other wish they could get help, to cure it or at least get rid of some of it.
Either way no matter what happening their should be at least something to always make you happy or sad, to me life is how you look at it.
