Apparent Competence.
This is a term that means you appear better at coping or more able than you actually feel or are. If you are able to cope in one situation, people assume you can cope in every situation. Whilst it makes sense why people would assume that, it really feels invalidating when people do it.
I always ask people this question when talking about this feeling that professionals don't care or that they are dismissed as not being "unwell enough".
Are you communicating your distress effectively?
I have met people who have been really upset but their body language and/or facial expression doesn't show it... AT ALL. They say how bad they feel but the observer isn't getting the message because the person isn't displaying the signs of distress. There is HUGE evidence that people with BPD tend to have a much smaller range of facial expressions when it comes to emotions and that this is one of the factors why they often feel unheard. If your body language conveys a different message to the one you are saying verbally, the average person will almost ALWAYS go with the non-verbal. Why? Because people lie... alot! We trust non-verbal much more than verbal communication because other people (before you have turned up) exaggerate, dramatise, lie, tell half truths or omit information. Then you walk in and the person in front of you has all of that experience in their mind and they will always look for signs that you are not being truthful.
That is completely unfair and there is a strong injustice in this and at the same time I can totally see why professionals have that tendency. If we see something too often we begin to make assumptions and generalisations about what to expect. Sadly the last BPD person may have gone into the local team or A&E and lied, threatened, dramatised etc and soon every BPD person is tainted with that brush. Unfair but also fairly human.
That's just my take. I am not a professional but know many through various interactions with them personally. I am giving a view based on my conversations with them. Hope this helps.
