Hi,
DH and I are very happy together. Occasionally though, we will have a row. Once or twice a year it is big, and the rest of the time small or medium. Sometimes after an argument my DH will have an episode of "hyper reality" - he will experience everything very intensely, see things very clearly etc. These episodes last about twenty minutes and he is terrified during them - he says he thinks his heart will stop, as it starts to beat very very fast. His breathing is fine.
These episodes often function as a way to end the argument as we will be in the middle and suddenly it will be "Oh my G-d, help me" and then I am required to try and jolly him out of it/keep him company so he doesn't feel alone. The row then ends. Interestingly it is never during or after a big row, only the small or medium ones, and only I suppose six or seven times a year. I was speculating that they might be panic attacks. He will not go to the GP. Anyone with any similar situations?
