People with full-blown Panic Disorder?

My sister suffers from panic and anxiety disorders. The first time she had one, she went to the ER b/c she thought she was having a heart attack. Instead, those f*ckers send her to a phyciatric hospital!! Later did she learn that she was not crazy but had the same problem as my father. She is currently on Xanax and seems to be much more under control. Good luck!!!
