People mistake self-worth with comfort of oneself or that they are somehow they define their self worth as worth less than others. The fact is, no one is worth more than anyone else. We are all essentially worth about as much as a grain of sand.
This overcomplicated self worth crap people try to get into it meaningless. You either accept yourself or you change your self until you accept yourself (accept meaning are happy with yourself), but you don't need to go and claim some self-worth. Being happy to be alive has nothing to do with self-worth, though being unhappy has almost everything to do with self-doubt.
