Define Peace

I am worried about leaving next year, being out on my own, not being here to take care of everything.
I realized today that as mom takes over the role of dad in my little family, I have shifted into role of mom. I don't know how I feel about it. On one hand, I know that I help mantain the peace of my household through my daily care-taker duties.
On another, I hold a certain anger against it because I, simply, am not a mom.
This just isn't my role.
I'm not saying that I'll never have children, because I do want them.
But, at this point in my life, I have not done anything to be put into the mom mold.

If I am away in college next year, who will keep everything and everyone together? Who will come to the rescue when I can't?

What if something were to happen while I am up there? I would feel so powerless knowing that it must be handled without me.
