I had the privilege once to attend a workshop conducted by Elaine Aron. There were about 90 participants. Imagine 90 people who are sensitive to various things - light, heat, proximity to others, scents, distractions; so many things including the placement of the seats. It took quite a while just for everyone to get "comfortable" so the workshop could begin. I learned so much about my own sensitivity but even more, I learned that many others share these sensitivities. And that sensitive people are not without humor, nor basic human fallibility. (Meaning, it's a way of being but not an excuse, especially for my own personal behavior). I've lost the book 'The Highly Sensitive Person' but it describes many useful tools for dealing with everyday stresses caused by sensitivities. I'd give it 5 stars. Her website has a checklist where you can get an idea if you're an "HSP", try it and see if you find yourself there.
