I haven't been properly diagnosed, but I have been monitoring myself for years and have come to the conclusion that I may possibly have BPD.

I've been reading up on the disorder and in one of the articles I read, it mentioned that people with BPD suffer from a developmental delay, usually about ten years, and that is the reason for the sudden outbursts and wild impulses. So for example, a 30-year-old would have the mentality and behavior of a 20-year-old.

In that same article, it also mentions that some experts don't even consider BPD a true disorder because it dwindles down by the time people are in their 40s and eventually becomes non-existent.

I just want to ask the community if anybody has heard of this before. How true is this statement? Do you feel that it describes your actions?
