Battle between Happiness and Unhappiness
Very sorry to say, perhaps, you are rather belong to unhappiness than happiness. But never mind at all, because I am not so happy perfectly too, like you.
Then from my petit experience, I will tell you some suggestion to be happy, at least as a success to be happy.
For example, from my childhood, I have been pessimist rather than optimist. Then, when I have lost something, very easily come to panic to find out.
But the result was always same, whenever the lost one is nearest of me.
Now I have switched from pessimist to optimist, because of "Communion with God," Neale Donald Walsch
