Hi gow! (I've just been catching up at the forums here in a scattered way and just read your posts... sorry for the delay.) Anyhow...

Bipolar and Borderline are NOT the same thing. Many people do confuse them. Without going into symptoms (because that is probably where it gets most confusing), the thing to remember is that bipolar is chemical in nature and it is cyclical. Borderline is a response mechanism and is a constant state of affairs (ie. not cyclical, not chemical -which is why it falls under axis II personality stuff).

Incidently, the abbreviations are BP for bipolar, BPD for borderline. (Because a lot of people mix this up, it can make for very confusing reading(!))

(And don't worry too much about the test. Short tests like that are covering so much psych ground they are really can't get down finer points that can make a big difference. As in "do you have mood swings" yes or no? It doesn't differentiate whether they are cyclical or not. Therefore, a check mark will go down for both conditions. See the problem there? That said, some people do have them both. Some don't. It's simply not within the scope of such a test to determine. Check with your professionals and, like blueoctober suggests, read up. They truly *are* different.)
