If you had a stable, supportive partner, you'd do just fine having children. It sounds like you do want them, but are terrified. You'd be surprised how maternal instincts kick in. I didn't know anything about having babies until I did it.

Of course if you choose not to, that's perfectly fine, too.

I think you're a person who draws people to you. So, as for dying alone, nah, you won't.
