Relationships-- and not just of the "romantic" kind, but also family and friends-- seem to present particular challenges for HSPs.
When I consider my own history, as well as the stories I have heard from scores of fellow HSPs.
Perhaps the best piece of advice out there is to be patient. What I mean by that isn't that we need to wait forever, but that we stay mindful of Elaine Aron's caution that HSPs tend to get emtionally involved very quickly, and very deeply.
