Marriage and Kids

I just found out that someone I went to high school with is married and pregnant. She's Mormon, but that is not the point.

Someone who is the same age as me is PREGNANT.

I haven't had to deal with this yet in my life. And it's not like I even know the girl or kept in touch with her, although she was in my prom group. 

I used to dream about being a mom. I would tell people that I was not sure what I wanted to do career-wise, but that I knew I wanted to be a mom. Now the idea of even being in a serious relationship makes me have a minor panic attack.

I can barely even take care of myself! How could I possibly support my husband, let alone a child! I told someone the other day that I am not nearly mature enough to be married and I truly mean it. 

God, am I more mature for realizing that, or am I actually immature? For my own sanity, I will go with mature.
