People who have really suffered from depression will understand the pain of depression.
Maybe other people think that people with depression are too sensitive and say that they are not in a bad mood too serious, but this is not the case.
I've seen people that made the situation easy when the topic is all about depression. It is true that people that experienced depression and anxiety will understand those that have felt it.
But to those that have never felt it, they'll never know how hard to beat it.
