Odd that they would jump to diagnosing as bipolar rather than depression. I was diagnosed as servery depressed years before it even crossed anyone's minds that I might be bipolar. I wasn't diagnosed as bipolar until I had a manic episode, but it wasn't nearly as severe as what I've heard of others experiencing (I just had racing thoughts, was still able to sleep about 4-5 hours a night) and I've only had about 4 of those incidents since then. They never last more than a couple days either.
