In the course of the past decade, I have often been asked if HSPs have "more issues" than the rest of the world.
It is one of those questions I don't believe has a straight answer. I think it is highly likely that HSPs-- because they spend a lot of time introspecting and processing their feelings and experiences-- more more likely to be aware of their moods and troubles, and thus are more in touch with the issues that bother them.
A large part of the issue seems to come from a dichotomy-- on one hand, HSPs often feel overlooked and marginalized by their families and greater society, while on the other, HSPs tend to feel more reliant on "feeling appreciated" to help their personal emotional well-being.
I am not a mental health professional, so my advice here is very much of a "layman" nature. What I offer on these pages come from the perspective of having been in therapy several times, and from talking to a number of people who specialize in helping HSPs, from Elaine Aron, herself, to life coaches who specialize in working with HSPs.
