31 weeks and water broke

I came into my local hospital last night for a small leak, falling expecting to be told that I peed myself and feel like an idiot as I left again shortly. Wrong.... turns out I do have a leak. I was immediately given a steroid shot and will receive another 24 hrs from the first. I was given a medicine rectally to deter contractions. I am also on antibiotics that will be repeated. I'll have an ultrasound in the morning and every 2 days until I deliver her. I have a beautiful 3 year old at home.. I have never been more scared in my entire life. They are trying to keep this baby, my second daughter, in til 34 weeks. I'm terrified of a nicu stay. I'm terrified of my 3 year old losing the only bit of normal she has left. This all seems so surreal. I slept for a couple hours and I sent all my support home but now I'm sitting here wide awake wondering about all the possibilities. Any similar stories or words of encouragement would be beyond awesome right now.
