Welcome to the Heart Bypass team! We're not the largest Sparkteam here (although growing), but I like to say that we've sure got heart!
Thank you so much for posting your story. It does sound like you were very lucky to be in the right place at the right time. And that's awesome that you're starting cardiac rehab as soon as possible.
Feel free to review the boards for posts that you find helpful or inspiring. My cardiologist did have to adjust my blood pressure meds a couple of times after my surgery as well. Experiencing stress after going through such a major trauma in your life is also normal. Yoga is the best tool I've found for managing it. But you may notice an improvement with cardiac rehab, even.
In the meantime, post questions, concerns, worries to the group and you may find others here who might be able to shed some light on things, having been were you are.
I'm glad you found us too,
Michelle, Co-leader Heart Bypass Sparkteam
