I have suffered from occassional panic attacks throughout adult life. It has been almost a year since my last one. A client came in for a quote yesterday. During our meeting, the sweaty palms, sweating, dry mouth, tightness in chest all started. I know it's not my heart. I have 3 emergency room false alarms to prove that. I perform live often with zero difficulty. Just out of the blue sheer panic! I'm off to the doctor in a few hours. Has anyone else here suffered from these?
