PLEASE PLEASE help me, I am really scared that I might have a terminal illness. So I am 22 y/o, and for the majority of my life I've been in excellent health. However, for about the last 5-6 years I have had some pretty bad anxiety and anger issues, due to OCD and a bad relationship with my brother. Now, I have gotten a lot better and am almost anxiety and anger free but I fear that I might have done some permanent heart damage from all those years of stress. I have had heart palpitations for the last 2.5 years, but in the last couple of months they have increased in severity (I feel some extra hard beats once in a while). I notice that my heart rate is about 90-100 even when sitting down, the only times when it drops to about 60-70 is when I am sleeping or lying down. Also, for the last 5 months I have developed a chronic cough, and I cough up clear fluid half of the time. BUT THE COUGH DISAPPEARS ALTOGETHER WHEN I LAY DOWN OR WHEN I FALL ASLEEP. Isn't that weird? My feet and ankles are not swollen, and about 2.5 years ago, when the palpitations had first started, I had a blood test and EKG and everything came back fine. Should I be worried now?? Have some of you had extreme stress for longer but have no heart problems? PLEASE HELP, AND I PROMISE TO TRY AND HELP YOU OUT WITH YOUR MEDICAL ISSUES FROM MY PERSPECTIVE.
