"The nurses were kind but I found the doctor rude"

Four weeks ago, I got very breathless and panicked. Prior to that, as I was walking out, I had to sit every few yards to catch my breath. I really struggled with that ever since and ended up in the A&E about four times. I was check out thoroughly each time but nothing was found. The nurses and sisters as well as all the helpers were very helpful and kind. However the night doctor was, in my opinion, very rude and said as much that there was nothing wrong with me, only a water infection and I felt they were quite willing to send me home. I found out later that I had had a small heart attack
