Yes, I also had the chest pains, blood press would go up, nausea and dry heaves and was totally afraid to be alone. My panic was 24/7 and the insomnia was horrendous. My doctor ran the usual heart tests, xray and stress cardio, eveything was fine. Then they put me on Ativan 1mg and Klonopin. The stress would go away while I was on the Tranq's. Finally I was put on SSRI and it is now gone. I was diagnosed as Major Depressed with severe anxiety.
