Hi Sami,
I was thinking about you and your event monitor so I posted in my journal about my experience with the event monitor (
here). Like you, I was very stressed before, and I was stressed during, too. Even after I got the good results, it took me a few weeks before they really sunk in. But I'm in a much better place mentally now, and have the energy back that I used to have.
Here's wishing you an event monitor that captures your worst, but the cardios tell you you're fine.
