Wow, is all I can say. I was 34 and having a great but busy year when I started the exact same thing. It took 8 Dr's to convince me I was healthy and just having panic attacks. I can't tell you the countless dollars and tests spent reassuring me I had no tumors, no cancer. I felt like I've been to lucky with my health and something had to go wrong. I went on zoloft for 2 years and it did help. Now I have a 4 year old daughter and I am having attacks all over again. I also feel just like you. I managed them without drugs for the better part of 5 years but now feel the need to be back on the meds. The people here are great and have given me really good advice and support. I also am new so I can only offer words of comfort and comradarie. You are not alone.
