Greetings from /r/ADHD ! I'm new to reddit and /r/BPD. I'm in my 20's, got diagnosed with ADHD when I was a kid but just got treated now. My doctors think I might have BPD.

&amp;nbsp;

In my ADHD research, I found a term called [**Rejection Sensitive Dysphoria \(RSD\)** (link to /r/ADHD post)](https://www.reddit.com/r/ADHD/comments/3xmmu4/what_does_rejection_sensitive_dysphoria_rsd_have/) in relation to ADHD.

&amp;nbsp;

This seems more like a BPD or NPD thing rather than an ADHD thing. Googling, I found some books that mention BPD and RSD together.*

&amp;nbsp;

Anyone heard of it? What can you tell me about it? (Back up with sources, please) Is it something BPD people have? ADDers? Narcissists? Does its presence imply a comorbidity of illnesses or the presence of a personality disorder? Is it something that could belong to one or more of several mental illnesses?
