What’s your opinion about mental health?

Yes. And people need to understand that mental illness must be treated the same way physical illness is. It is called mental and not emotional illness for a reason. Your brain is nothing but an organ, just like your heart, liver, lungs and everything else that would cause you any physical illness. Mental illness is physical illness with symptoms that are expressed differently. Therefore, the "sadness" many people seem to think is the cause of depression should be treated/viewed as the result of it (a symptom). Your environment and experiences can and will definitely affect your mental health but it is still chemical imbalances we're talking about. And that's why both therapy and medication are equally important.
