I don't know where, but I think that you could maybe get into a program if you address the low GPA in your statement. So it's about saying "hey, I'm aware of this shortcoming" but then "let me tell you how I resolved the issue(s) that caused it and why it won't be an issue in the future." Also, if your grades improved that last semester you can use that as an example of ability to succeed academically once the Bipolar was addressed.
 

I agree with Louise to bring it up in your statement.  However, I would not overly focus on it.  I knew someone who dug herself into a hole by over-addressing it and basically mentioning that she had a low GPA because she couldn't keep up with a full-time undergrad course load, while she was applying for a full-time Masters, which tends to be more academically rigorous.  So, bring it up, briefly address it, and then move on.
But I think you have a shot.  Someone in one of my classes mentioned that she was on provisional status this semester (our first semester) because she had a low GPA.  In order to remain in the program, she has to have a 3.0 GPA by the end of the semester.  So, schools definitely don't just look at your GPA and a low one wouldn't automatically disqualify you.

You can also discuss what you learned about yourself, and systemic problems you want to professionally address, as you went through the mental health system - how you learn, barriers to recognizing and getting appropriate help, etc. That can actually be a powerful personal story that shows a lot of appealing traits to the adcom.
