Yes it happened to me Mally. The children were 3 and 4 at the time . I know what triggered mine, it was a friend of mine collapsing in the street, her 5 year old son was with her , she died that day. somewhere In my mind I thought the same thing was going to happen to me. When I had the first one my OH called the Doc because we both thought I was having a heart attack! She explained about panic attacks and gave me tablets to calm me down. Like dave we didn't tell anyone, I felt so ashamed(silly I know) I took the tablets for about 18 months until I conditioned myself to accept them for what they were. Once I did that I was able to relax, breath through them and let them wash over me . I do hope they don't last too long Mally . this could have been triggered by your Daughter's recent battle with cancer. Xxxx
