Well, it seems clear by the votes in this thread that at least one person just HATES all the answers provided, no matter how good they are. So hey, fuck it, l'll throw in my 2 cents.
This sounds like scammy bullshit to me. l fit some of the criteria too, most notably that l am also very observant and aware of my surroundings and those around me, so while l don't get overwhelmed like l used to and have learned to deal with it, l am very tuned in to the events and emotions around me. This is usually a blessing when l can cue into someone who's having a rough day, or see trouble brewing before others do, things like that. And l'm sure that being this way for most of my life probably earned the label 'intense' to some, though l'm a big old extravert and nobody would ever consider me shy or timid.
But do l believe in the HSP? No. l would generally call these traits 'human'. Someone years ago once directed me to a site about lndigo children, who are described by Wikipedia (and various other sites) as such:
"Descriptions of indigo children include the belief that they are empathetic, curious, strong-willed, independent, and often perceived by friends and family as being strange; possess a clear sense of self-definition and purpose; and also exhibit a strong inclination towards spiritual matters from early childhood. Indigo children have also been described as having a strong feeling of entitlement, or "deserving to be here." Other alleged traits include a high intelligence quotient, an inherent intuitive ability, and resistance to authority.[4][6] According to Tober and Carroll, indigo children function poorly in conventional schools due to their rejection of authority, being smarter than their teachers, and a lack of response to guilt-, fear- or manipulation-based discipline.[7]"
Almost every adjective and descriptive here applies (or applied as a child) to me to some degree. However, after reading more on the topic, it just started sounding cultish and weird after a while, and if nothing else, seemed to have no purpose other than to sell books to parents who thought their kids were special or needed some sort of validation that they weren't shitty parents. The whole HSP seems this way to me. Not to mention that there are other disorders (Aspergers comes immediately to mind) that mirror many of these same traits/characteristics, so why wouldn't the HSP 'diagnosis' fit one of those other social disorders first? And why are they writing separate books for all of this when they could just stick it all together and be done with it? l'll tell ya - money.
Yeah, this just sounds fishy to me.
