I made a post a few hours ago about having a bad first interaction with a psychologist, it was the first time I had ever talked to someone about it. I had been researching it and it sounded a lot like me so that's why I approach her. She made me feel really confused. If you want you can look down my post history to it, and what she told me.
But now, I'm confused and I think I might have a misunderstanding of what the disorder is.
I identify with all of the symptoms on the DSM that I've read about, but a really prominent one is having a very roller coaster sense of self-identity.
It happens to me a LOT. And just now was the perfect example. I was talking to a friend and got really upset that he took a while to reply every time (overreaction I know) and told him just now that I wanted to kill myself and that I was stupid (because him not replying means I'm a stupid person, a bad person, a person who isnt interesting). For about 10 minutes I was just actively planning to kill myself just now. Then I was listening to my ipod right now and a song came up and reminded me of a class I'm taking where I got a good grade on the test. I instantly smiled and felt like the smartest person on earth and felt really really proud of myself.

My understanding of one of the many aspects of BPD was shifting mood, mostly from borderline sad about everything to instantly extremely angry or instantly extremely suicidal, which is always activated by stress or having an interaction with a friend and something very slight "goes wrong". And, that causes a really scary change in self perception and understanding of who you are as a person.

I'm not asking for a diagnosis. I'm just asking for clarification of whether or not that is what the disorder consists of (at least in part?), because the doctor made me feel like I misunderstood the disorder. She told me, "you don't have BPD, you just have a lot of suicidal thoughts and tendencies triggered by stress and a perceived slight in an interaction makes you feel very angry and impulsive."
I'm confused because to me, she just said "you don't have BPD, you just have..." and proceeded to give me a definition of BPD
I'm really confused :( :(
