Yes, I can identify with what you are saying. I am very emotional and tears are often triggered. National anthem, seeing Christ in the faces of children, seeing kindness and gentleness done to others. Also irritated by little noises, as you say. Have to have it dead silent for studying, etc.
Feel music extremely intensely, sort of in the upper abdomen (I know that sounds weird!). As a teenager I used to play for hours on end and it was a huge emotional outlet. Don't do it now because of anhedonia and back surgery so I can't sit long. But all that emotional power is still there, and I feel like an unexploded bomb.
Everybody says I am hypersensitive, and that I also take on other people's problems and identify with them/worry about them.
I think the strength of feelings is the upside of BP and the oversensitivity is the downside. It certainly would be easier at times to be 'normal' and 'thick-skinned'.
