If we say I hate myself, why?

Maybe you forgot the main purpose in this life? you stop doing good things? you do not believe in love? or you lose a lot of friends because of your own behaviour, or you've got a sense of regret that in, and you don't despair and feel this life is over, sometimes also feel alone feel unnoticed by family, we can easily say: I hate myself, or even you have no money and returned to say: I hate myself, have stopped saying as last, began to say, ' I love me, and immediately tried to do the best thing and see people more suffering than us, and feel how lucky we are today or anytime.
