From the literature I have read on the matter, it seems like a stamp anyone can give themselves to rationalize their inability to cope with life. I mean, the sheer number of types of High Sensitivity is staggering.
Fortunately, this fashion trend has already passed. It is soooo 2013 to be Highly Sensitive. I understand gender identity disorders are all the rage nowadays.
On a different subject: anyone been listening to the lastest Khruangbin album already? Sounds fun, doesn't it?
