There is nothing wrong, sometimes some of us have sadness and despair that we can't find the reason for. When we spend our time looking for reasons, we'll find them and the despair can be made worse by this.

It's hard for some of the people we meet or spend time with to understand depression or despair when they only see reasons for us to be happy. Of course we want to be happy, but we can't always see the reasons others see.

One of the things that works for me is to accept that I am in despair and that there is no reason for it. Once I accept it, and that I cannot change it, it begins to go away faster.
