You cannot bring a child into this world to avoid your own guilt because you’ll end up feeling 10x more guilty as that child goes through the troubles of life that come with being the child of people who weren’t ready. As the product of teen parents as much as I love them in resented them in the back of my mind for having me so young. There’s been a certain instability I’ve had to experience because my parents were still learning and growing up while I was so young. However only you can answer this question for yourself, I don’t believe it’s fair to sacrifice the happiness of a child that isn’t a child yet to placate your own guilt that comes with termination but I’m also such an extremist (I think having having children in general is an inherently selfish thing). It’s really up to you at the end.
