FIrst time mom.

I am a first time mom and I'm being induced right now at 38 weeks and 1 day due to preeclampsia. I've been on magnesium to avoid seizures and pitocin. I'm very nervous the nurse has stretched me out and I am now 4 cm and the doctor is supposed to come in around 3 more hours to break my water. Has anyone been in this situation if so please tell me how to cope and deal with this I'd appreciate it so much.
