My anxiety started whenI was 17 after my daughter was born. It would stick around for a year or two then vanish. It did the same thing after my other three kids. I remember going to the hospital 50 times in one month because I knew they didn't know what they were talking about. I was at the doc every week. Now have a one year old and the attacks are coming on strong. It affects mt bp and hr. The highest my hr ever got was 111. Today I was walking around in KMart and I felt dizzy. I stopped to check my bp ans it was 145/94 pulse rate 105. But I could feel my pulse getting lower as I rested. This is the first time panic has kept mt in the house and stopped me from driving. I had to get an at home job because I knew I wasn't going out to work. Hell I am terrified of the grocery store. My kids are the only thing to keep me going.
