This is really frustrating for me so I am going to try to keep my shit together for this post. 

As someone who has been professionally diagnosed, I am having a really difficult time understanding how/why people are self-diagnosing and why you think that that is okay. 

It is difficult enough to have your diagnosis taken seriously.. It is hard enough to see article after article about "How to tell if your ex has borderline personality disorder" and the like.. So now in addition to this already turbulent arena to navigate, there are individuals diagnosing themselves and posting on BPD forums and and and and and...

I don't get it and I don't get why you think it's okay. 

I wouldn't self diagnose myself with cancer and then show up to their support groups and take up their forum.
