is it bad for me to want to have baby when I am only 19?

This has been on my mind a lot. I feel jealous around some of my friends because they have children. I dont want to have a baby because they do but I want to have a baby because I want to have a baby. I wamt to be able say look at what my son or daughter did and to be able to give them the things my parents didn't want to do with me. I also want some who is going to love me even when they say I hate you. Is this bad??
