I know how shitty it feels when you think your hospital visit was a waste of time, but what if it was something of concern and you didn't go in and things went downhill fast? That's the trouble we never really know and sometimes gut feelings are wrong. A few times I thought I was fine but i wasn't and ended up in hospital for a week. One time I thought I wasn't fine and spent the day at the hospital being tested only to be sent home. I really am sorry that you had a bad time today, but I am glad that you are well enough to go home. Take care of yourself. Sending you virtual hugs and chicken soup
