I know that you are trying to help, but I strongly feel that your comments are very inappropriate. One thing that you need to understand is that people with BPD are born with a genetic trait that causes them to experience emotions more strongly. Once someone who has this trait experiences an invalidating environment, such as an abusive environment they become at risk for developing the disorder. Learning to regulate the intense emotional experience that comes with BPD is not something that someone can do on their own, and it takes a lot of time, and special validating environment in therapy. Marsha Llinehan who has BPD and invented DBT says that a person would have to be super human to cope with the intense feeling that people with BPD experience with out leaning any supplemental skills.

Furthermore, only invalidating people with BPD only exacerbates their feelings, and does little to help them grow (research has shown this). Growli has made huge progress by contacting therapists and she deserves to have that validated and celebrated. This is the single biggest step I have ever seen her take towards helping herself. You might also ask yourself why it is that you think that you need to intervene in the way that you did. Why did you not just have an empathetic relation and think about what kind of feelings might cause Growli to post such a thing. Perhaps your own anxiety about your feelings of emotional inadequacy are subdued when you find that you can view your own emotional progress as superior to another's?
