Good write up. Over sensitivity or hyper sensitivity need not be a self-destructive trait though. I know I"ve always had a high level of emotional sensitivity. This has meant that it was easy for me to be drawn into other people's emotions in the past, but with a strong person grounding it's also been of huge benefit to me.
For instance, I can read people very well, which was a huge benefit when I was working in sales. I can build rapport with people very well and I can also pick up on things that are troubling people, or use it as a warning system against dishonest or unscrupulous people.
Emotional sensitivity can be a huge benefit, it just means that people who don't have enough self-awareness to separate themselves from other people's emotions can caught up in their drama.
Great write up, mate.
