Ramblings

I decided to be open about my condition to a friend (he's studying psychology), I told him I had BPD, he said I didn't because I don't express it. That I may have personal problems but not BPD; that someone else he knows express it and it looks nothing like what I have (I was lucky enough to not pull me down through the "you're not *something* enough" spiral of hell I usually am in when I hear those words.)
It's the first time I talked to him about it and his reaction kinda bashed me.
How am I supposed to be like to prove that I have it? Have a breakdown? I know I have a socially functioning persona, but is that a reason to, somehow, invalidate my dissorder?
I'm sure he didn't mean to be agressive about it, but what am I supposed to do about this?

I haven't fell down through the "guilt spiral" yet, so maybe that's why I'm feeling weird about his point of view. But I'm actually surprised. I didn't feel like this since I had to prove stuff to my parents so they could let me have the things I wanted (they never accepted any of my reasons).

Has it ever happened to any of you? What did you make of it? Should I not bring my dissorder out to him again?

yes i feel invalidated too,and i have notice others do.is crazy that we need to be diagnosed with a pd to feel validation of our pain.it doesn't mean you don't have pain. and maybe practically is better if you do not have it.maybe you have better chance in getting better.and it also means you are less bothersome to others.
i have read even crazier , with npd that want to have it because they feel weak if the don't.and want to have it to belong.instead of wanting to get rid of it.
also is just his opinion.you know how many times i have read people go to therapist and different therapist said different things or didn't want to diagnose them.psychology isn't like science exactly.
you can't have that kind of proof to know things.is descriptions of personalities,is very theoretical.
maybe in his mind is something bad,and it feels it will make you feel better if you don't have it.

don't let people provoke you to hurt yourself to prove something to them.i often felt like that and is sad that it takes to completely destroy your life for people to notice your pain.and even then they do not really help ,they just admit you are destroying your life.it is never about validating your pain. noone cares.is about how much self destructive and bothersome to them you are.
it feels so helpless.

I agree with julllia. People can believe what they want, but they aren't always right. Especially when it comes to yourself. The person who knows the most about you is you so you shouldn't let people tell you who you are. And just because your friend is studying psychology doesn't suddenly make him an expert on personality disorders either.

When people pretend to know everything or are arrogant it really irritates me too, but don't dwell on it. Just say "Whatever dude." and move on. When people are trying to be genuine a-holes (which, I don't know if your friend was aiming for, I don't know your friend) I tend to give them the finger.

Thank you. Reading both your responses helped me calm myself a bit.
I guess I was mostly shocked that someone like him wasn't as accepting as I thought he would've. At first I thought he would be much more comprehensive of my dissorder but he ended up being pretty close-minded .

Yeah I think people tend to draw their own conclusions and it's hard to dissuade them from their convictions. It also goes the other way too sometimes. "Oh you're totally BPD dude. I can see it!" People are funny, that's all I can say.
