Hi, I'm sorry if this isn't the place for this, I wasn't entirely sure. I'm not looking for a diagnosis of course, just curious about some stuff. About a year and a few months ago I spoke to a psychiatrist (I also speak to a counselor fairly regularly and sometimes on and off for the past 4 years) because I was concerned about some of my behavior and thoughts. I have had fairly severe anxiety since I was about 8 years old, and I'm 20 now. I had noticed some stuff that was fairly different from my anxiety, which I know very well. He came to the conclusion that I had borderline personality disorder tendencies and that I should just keep doing what I'm doing and continue talking to my counselor. This was confusing. At the time I had expected to hear that I might have been bipolar, and it even seems to run in my mom's side of the family. To be fair I had not entirely opened up the way I maybe should have in that appointment. 
My question I guess would be, does everyone with BPD have all or a lot of the symptoms in the extremes? Because I feel that I'm still a fairly quiet person and I maintain my job and my relationships in my life. My anxiety does make sure that I don't miss a shift if possible though so maybe that has something to do with it. I did miss half a year of my high school, but I had figured it was anxiety but I have such a skewed sense of myself that I'm not really even sure. 
I have thought about this quite a bit and I dont take it lightly. I have a large amount of the "symptoms" of bpd, and I'm not one to self diagnose whatsoever, so I won't. 
I do feel a lot of the "symptoms" but I don't necessarily act on them. I just sort of drive myself a bit crazy thinking about them almost 24/7. I do impulsive things but not necessarily extremely dangerous ones. But not healthy things either.
There's more but I don't want to ramble and make it seem like I'm asking for a diagnosis. I'm just wondering if it's possible for someone to have BPD and still be a fairly reserved person towards others? It does affect my relationships in a way that's mostly internal I'd say. I'm terrified that everyones going to leave me and when people do I don't handle it well on my own. 

Again I'm so sorry if this upsets anyone or offends anyone. I know I could ask my counselor these things and I know I could call my doctor too but I was just curious. I will be talking to my counselor soon. Thank you!
