Here I am!! Yes, yes, you are not alone with HPD. There are reasons I haven't been here much: I have learned to cope well (therapy and EMDR), and am learning to recognize what triggers an HPD episode of very typical HPD behaviors, and I have been sort of avoiding PC, as it made me feel all-consumed by my disorder when I was on here a lot.
And, let's be honest, HPD women can irritate other HPD women. So, no surprise that we're not all bonding here like they do at the BPD forum, etc.
But I am here - though not often - and I have been, rightfully so, dx-ed with HPD a year or so ago. Yes, we exist.
