My most recent diagnosis (I think) is Bipolar I with Histrionic Traits. They have never "mentioned" borderline (at least not to me, my parents say they have to them, and don't even think I'm bipolar?) but having a PD diagnosis has always made me uncomfortable. There is definitely something wrong with my brain, but I don't want there to be something wrong with my personality, you know? For some reason my dad seemed happier that I had a PD diagnosis rather than bipolar. When I was in the hospital last time (considering the reason I ended up there, it looked like a BPD episode) he actually said "but that's a good thing! It means you don't have a disorder!" Um, really dad? Cause I'm pretty sure that would have to mean you guys were shitty parents (this is the consensus of all three of their children and virtually everyone... except them, of course.) But I will say that DBT has helped me a lot more than any other kind of therapy I've had. I was so angry for so many years and I just didn't know how to cope with such a fucked up childhood on top of all the crazy shit I did while I was manic/psychotic that got pretty much the whole world to think I was a piece of shit. I only actually "had" DBT during the two times I was in the hospital, but I've used mindfulness techniques on my own during the times I felt overwhelmed with emotion. Which has been... basically my whole life.
A lot of the time - I think in part to several of us also being raised by mentally ill parents who fuck us up - it's a little bit of both disorders. Even though the doctors told me while I was inpatient just a little over two years ago "we don't know if you're bipolar or you're not", they still wanted to pump me up with medication. I figured if I wasn't bipolar, this was bullshit. And then I turned 26 and lost my health insurance. So I stopped taking medication altogether, and while I found myself able to think more clearly... everything eventually fell apart. I knew I had to get back on.
That was just a few months ago, around when I joined this sub. At the time, I was homeless, jobless, and completely at a loss for what I was supposed to do in life. I'm still figuring shit out, but like I said... I'm better.
