People with this disorder think one of 4 things.
1.they are dieing
2.they are having a heart attack
3.They are going crazy
4.They are going to faint
My personal issue is fear of going crazy, but actually, panic is the exact opposte of going crazy; you are so in touch and sensitive to reality that you panic. Crazy people do not fear going crazy, they live in a world of unreality, and cannot reach out for help, as you are doing by being on this site.
Are you in an abusive relationship (husband, boyfriend, boss) or anything that is causing all this stess? Best wishes, cathie
