I am a failure, life has been unfair to me, I deserve only bad things in life, these are some of the examples, when a person feels sorry for himself ,herself. Self pity feeds on itself. When we reckon a sorrowful image and a lack of faith, things tend to go wrong, which will give you more reasons to feel sorry for yourself. It is a vicious cycle and if it continuous long enough, you run the risk of appearing pathetic and miserable.
