Hi Anthariamac and welcome to the forum.
I'm not surprised by what you're saying. When I went to my first psychologist (as recommended by my GP) he refused to tell me what he was treating me for, even though I soon realised he was going over all the criteria for BPD. I was already pretty sure that's what had been plaguing me much of my life. I was soon diagnosed by two separate psychiatrists after many misdiagnosis in the past.
As many others know on here, I'm a mental health nurse and I've done a bit of "nosing about" since my diagnosis to see how other MH nurses react to someone with BPD. As soon as you mention it, the shutters fall behind their eyes and some of them get quite defensive. Of don't worry. Discrimination is alive and well within the service alright!
This still continues to frustrate me and had led to acts of self harm because of that frustration. I'm actually feeling very low at present because my mental health "team" are soon going to dump me and leave me to cope as best I can. It's causing me major abandonment issues that I just can't seem to get over. I usually bounce back from depressive episodes quite quickly, but now can't even find a reason to get out of bed.
Anyway, stay strong and search out someone who can help you. They might be few and far between, but they are out there. All the very best.
Ellie.
