Visit to the ER -- but oddly uplifting

On Saturday I was at dinner with husband & friends when a strange, strong feeling hit me in the upper chest. It wasn't pain or even shortness of breath but more like palpitations. We decided to go to the ER. Long story shorter -- because of my heart history (angioplasty resulting in 4 stents in 2 arteries, 2010) they kept me overnight for observation. It was scary and uncomfortable, of course, but by early afternoon Sunday they'd released me after all the tests were negative.
And for whatever reason I feel really great today.
One thing I learned was that compared to the others on the cardiac floor -- not just this weekend but overall what the nurses see -- I was the youngest and by far healthiest person. My night nurse, who checked me in including weighing me, said that my weight was "perfect." Sunday morning I was so bored that I walked the halls in my hospital gown and a pair of sweatpants, and I saw the misery and unhappiness people and their families were going through.
It made me feel fortunate, and also because we have excellent health insurance coverage, so that this episode won't cost me a dime.
Also I had nine hours of catch-up sleep last night, which I'm sure added to my feelings of vigor and a very upbeat mood today.
You'd think that a visit to the ER and being admitted to the hospital would be overall a bummer, but it didn't really turn out that way.
