officially in labor

I'm 26 weeks & 6 days. I went into preterm labor at 25 weeks. I was dilated 3 centimeters, we have no idea why. They admitted me & put me on bedrest. Today my water broke................. I'm a first time mom ............. & IM SCARED AS SHIT! WHAT IF I LOSE HER? I DONT WANNA WATCH HER SUFFER! HOW BAD IS THIS GONNA HURT? WHY IS THIS HAPPENING TO ME? I just burst into tears. I'm so tired & heartbroken. Idk how to relax. I'm not ready. I didn't even get to prepare. Omg. Please pray for me or something!
