Have been DX'd in the past with borderline AND "soft" bipolar. This fits me almost to a T, especially impulsivity and anger. I don't really have identity issues.

I just spoke to a therapist on the phone to whom i descr. my symptoms, and she said she believes there is often overlap.

Mainly, i just can't cope. Especially with anger. In fact, all the shorthand I'm using rite now is because i broke my right hand by smashing it into a door in frustration two wks ago.
