BPD realisation...

So i recently stumbled across this forum.. and for once felt comfortable about being able to express whats been going on regarding my mental health. I have no idea where to start but ill start where i realised all that i have been and all that i was putting my partner through was far from normal (and right)...
I work in a mental health program and came across one particular referral that really struck me hard. She was diagnosed BPD, and we dont get to many BPD clients so i wasnt really aware of the symptoms. Anyway i read hers and my heart felt like it was beating outside my chest- there was a huge moment of realisation. I didnt know what to think or what to believe about myself... anyway from thst moment on i did research daily, and ever past memory of all the symptoms i displayed not only to my partner and exes but friends also... i began to question...
I told my Gp of my concerns (as at this point my partner had just about enough with me and my behavior/ emotional instability) and got hooked up to a psychologist...
I've only seen her twice now and when i asked if i could be diagnosed she questioned me askimg why? I was a bit thrown back and annoyed by this but is it wrong for me to know whats wrong with me and if i really do hsve BPD? Thing is i wholeheartedly believe i do and i match up to nearly all 9 critieria. Im going to give her a couple more times and take it from there...
Anyway just really wanted to voice this out:) if anyone has been in a similar situation please feel free to mention it:)
