 Are there any actual causes of RSD? And people are not necessarily clear on this. A lot of the hypothesis about why it could happen is likely due to past experiences. You know, obviously if you've grown up feeling like failure and rejection is not right and it's not an okay thing to experience as a human being, it's something that you should avoid at all costs or you perhaps have some unfavorable dynamics with friendships or romantic relationships or with parents even. Then it's likely that that could be a source of developing RSD. But there have been some discussions about the co-occurring factors in someone developing RSD. It tends to be individuals, as I said before, with ADHD, attention deficit, hyperactivity disorder, but other personalities and mood disorders too.
