From what my psychiatrist has told me, it is possible to have both. I do know that splitting on people is a huge part of borderline… but not so much the bipolar. And from what I’ve read, the borderline mood swings come much faster and more intense than with bipolar. That’s what I’ve read… I don’t personally have it; I do have unspecified bipolar. I would definitely recommend talking to a mental health professional if you can! 🙃

A mental health professional would know best, but from what I've heard, with Bipolar you get times with euphoria and you feel extremely happy but it's not good since it gets you to do things you regret doing. I personally don't have bipolar but a mental health professional described it like that for me.
