That's true, but if you recognize like all the signs for HSP, you will probably are. Non-HSP'ers will not recognize much of the traits.
Sure, but the question I have, and one of my main criticisms with psychiatry in general, is that it reifies the problems that it deals with. In other words, it treats being a "highly sensitive person (HSP) as a "thing." But is it a "thing," or is it an experience of life. Moreover, I would be more interested in what, physiologically, is the source of the high-sensitivity, and what, if anything, can ameliorate the issues. I mean, yeah, I identify with the description of an HSP, but I also identify with the description of about half the diagnoses in the DSM as well. I find it ridiculous to think that I have all these conditions residing inside me, or even many of them. I'd rather just get to the chase: what is the problem, what is causing it, and what, if anything, can I do to ameliorate it or make my life more bearable or livable.
