@badmac , I can relate to you completely! My story is so the same as yours. I was going to cardiologist since my early 20s. Also said I had a heart murmur. Always did testing but never found anything. Finally after my younger brother who is 16 yrs younger then I fell over playing basketball at school,he was 16 then. We discovered we had the genetic for HCM. My brother did survive. Which they say was nothing but a miracle after being in a comma for weeks. Long story short, since then I have been on many medications for HCM that seemed to be controlled very well untill about 4 yrs ago things started to change and it was like the medications were no longer working. I started having many symptoms from severe fatigue, strange heart palpitations, very bad head fog, dizzy like being drunk & I don't drink lol, to passing out a few times. My anxiety has no doubt become worse also. I had testing done all day on may 31st at Mayo MN. Today is Sunday June 2 and as I lay here crying this morning writing this I am having severe anxiety for my myectomy tomorrow! I thinks it's all the what is thoughts going through my head and I feel scared also wondering if I'm doing the right thing. I just turned 57 and even considered leaving the hotel and going home last night. Lol. Thank goodness for my family here with me or I may have been gone. But I read everyone's post's and it does help relax me. I've decided to stay and will call tonight for my surgery time tomorrow! They say I am in the best hands with Dr Shaff. So yes I am freaking out but I'm gonna try to stay positive and believe this is the right thing to do. Blessings and much luck to you!
