I know that there several national support networks that would be of help to both your husband and yourself. I had panic disorder many years ago and I found that the books of Dr Claire Weekes were immensely helpfull,that along with a very sympathetic therapist may help your husband onto the road to recovery. Please give him as much positive support as you can -it is vital to his recovery...unfortunately I did not have that.Regarding children-maybe that is what he needs to distract himself from the fear and anxiety.Good luck to both of you
