Hi Violet -- The owner of the website to which a link was provided also has books about the highly sensitive person.
Highly Sensitive Person book
I stumbled on this book by accident in a library. I was already in my 50s. It explained so much about the experience of being high sensitive -- it explained me to me.
One thing that has helped me is having a white noise machine for when I sleep. I take it everywhere with me. It really helps in a motel when there are extraneous noises in hallways or any unfamiliar place.
My brother is the same way. I think my mother is, too, but she will never admit that she is not John Wayne. Wink.
Good thread.
