I AM FREAKING OUT!!!!

I'm due next month on the 25th and the closer I get to my due date, the more I get scared. I just realized today I'm 4 weeks from bringing someone to the world. But that's not the scary thing, I'm freaking out about the pain I'm going to go through, how long will I be in misery? By misery I mean labor! My heart starts to beat fast and I almost feel like I'll get an panic attack when I start to think about it. I've never really put any thought into it until recently. I'm extremely scared about what I'm about to go through.
