Well, the MI, all by itself, is going to mean 'learning' novelty in your system. You're not the same, not after the event, and not after its remediation, also novel....and intrusive. So, it stands to reason that you are not going to feel the same, and in view of the nature of those events, probably not in a salutary way....or a in pleasant one.

Then, putting those aside, how active have you been in a normal way since the MI? And then, since the impositions of your repair and the following regimen of self-care? How mobile, how much positional change that you have avoided due to discomfort lying one way or another? See what I mean? You're not the same person you were 10 days ago.

I feel your message to yourself should be, 'That was a doozy!. Whew!. Let's take a slow for a bit, be patient, and let our body find new 'normal.'

And I wish you the very best of success...and luck if it will help.
