Oh yes, that's right, helping others and the world can also help improve our mental health. That's where finding our purpose and the meaning of life comes in.

I didn't want to just focus on a specific mental health problem because it is indeed such a wide field as you mentioned. Some mental health problems can be a big problem than others but that's where it all starts, in the mind of people with unstable mental condition. There are billions or more people on Earth, add it all up and it becomes a problem. People can focus on any part of it that each of us thinks need more attention. :)

Actually the theme is for most important issues... And I think generally it's a big issue too that people need to look into and find the parts we need to deal with. :)

This is my way for people to know more about it as I agree that we all need more information on it.
