I can identify with so much of what has been shared in this thread. I have lived with panic disorder, ocd and depression since my teen years.... and I am now 73. I have taken a small dose of xanax for many years, and about 5 years ago my PCP put me on a 1mg extended release xanax that seems to have helped immensely. He still also gives me 0.5mg tablets to take in the event of an attack, PRN, but the extended release keeps some in my system throughout the day. My mother died of a heart attack at age 81.... my father never had cardiac issues... Which genes did I inherit. Recently I was diagnosed with a brief episode of paroxysmal AFib while wearing a monitor for three weeks and subsequently put on Eliquis and Flecainide. I seem to have adjusted to those with no major issues, but now my ocd is focused on my heart.... and a possible heart attack.... and I wish so badly that I could just "let it go" and live my life without the worry. I notice any little twinge of pain in my chest area.... which is probably related to the anxiety. I do see a cardiologist regularly.... several years ago had a CT scan of my heart to check for blockages and the results were okay. I see a therapist monthly.... and I use breathing techniques to calm when the anxiety gets bad. At 73, I know most of my life is behind me... and the end could come at any moment. But the anxiety and ocd will ruin whatever time I have left. My best wishes to ALL who live with panic, anxiety, ocd on a regular basis. You are not alone!! Mike
