"maybe you aren't a runner anymore." - my yoga instructor, when I expressed frustration with my ability to run So far? She's been right. Running is a bitch. I can do it. Sort of. thing is, I can walk 6 miles a day without any problems, and I enjoy it. Rather than focusing on what you can't do and how it's gone, she opened my eyes to focusing on what I can do and what that means. Once I turned around to "hey, you're not dead, and considering what the EKG looked like a mild dose of blood pressure meds is an extremely small price to pay" I found better ways to be present. By the time my pulse-ox made it back to 99 I'd pretty much found a new groove. It sounds like you're on your way. It gets easier once you've been given an excuse to suck. Find the groove but more importantly, be willing to re-find it whenever the need strikes.
