Sue,
Wow, I'm going through that now. I am 32 weeks pregnant and have suffered from panic attacks for 14 years. This will be my fourth boy and the first three pregnancies weren't all that bad but this one has been. I can't sleep, I feel like I can't breathe, and I dread the night time. The OB put me on paxil but I just started it two days ago. From what my OB told me, as well as our pediatrician, that paxil is relativly safe during pregnancy and can be used while breastfeeding as well. You could talk to your doctor about taking something that is safe during pregnancy. If you need to talk anymore about this, I'm here for you.
To Lauren,
I am so sorry to hear about your miscarriage. My thoughts are with you. (((Hugs)))
