I Don't Deserve Life

I've heard multiple times during my life from my mother saying that I was on life support for 3 days when I was born, and for some reason only until now, this day, this night, as I was laying in the bathtub, I realized that I should've been a dead baby. I never thought of it before, or gave it much weight or importance until now, because of the thought that if I was born 100 years ago, when medicine wasn't as advanced as now, I would've literally died at birth.
I don't deserve this life, it was a gift ...a gift I don't know how to accept.
I'm having an internal crisis right now, because I don't know how should I live my life with this realization. I shouldn't be here, I should be dead. Part of all these people's lives...but I shouldn't exist now. You shouldn't know me. You shouldn't be able to see or read this.
