I don't know if it's quite the same thing, but often I also question whether my parents should have had me or not, and why I am actually here in the first place.
My parents couldn't conceive, they hate each other, and should never have been married. My mom conceived me by IVF, and I often feel like they just had me in order to say they had a child, especially my dad, he is the kind of person who would do that.
My entire life has been a sense of being the "fifth wheel" if you know what I mean. I feel isolated and never ever part of any kind of group, like some kind of loner or renegade, wandering the earth and never finding a place to call "home". I feel constantly like I should never have been born, like it was some kind of mistake.
Wow, but your mom actually saying that, I'm so sorry.
