Is it normal to be diagnosed with borderline, and to experience all of the symptoms, but to have stable interpersonal relationships? 

I have close friends I've had for years. I've never had real problems with those friends, except a couple times but they weren't extremely chaotic or anything. These are people who also have mental illness, including a friend who was told they had symptoms of BPD By a psychiatrist as well. 

It confuses me because one of the most common symptoms seems to be chaotic, unstable friendships. 

Me and my partner are a whole nother story. Its really bad, I'm freaking out about things daily with him. It is a problem. 
Part of me is a little curious as to if maybe it can manifest only in certain relationships. 

As I type this, I am recalling recent moments of feeling worried that everyone hated me, and crying about it. And even posting to social media, "it feels like I've ruined all of my friendships and it's all my fault." Which I know is toxic af ,but it felt that way at the time. 
So I'm starting to think maybe it does manifest in friendships a bit. But this is all that happens. It can be a little intense, but usually it's not so bad. I never take it out on them or start anything with friends. With my partner, I start arguments &amp; seek constant validation.

*But yeah, I guess I was wondering if anyone else who for sure had BPD has stable decent long lasting friendships with people they genuinely like. Is that actually uncommon, or are the people who talk abt BPD online just negative and uninformed?*

 
*Maybe I've read too many stories by non-borderlines, and have also misinformed myself into thinking I have to be completely incapable of any emotional stability or maintaining a friendship because of what stinky redditors have to say in order to feel accurately diagnosed with the disorder.*

Any input appreciated lol
