bipolar ii symptoms

Been diagnosed with depression, but I wondered if they have bipolar II?
I was diagnosed with depression recently, but after reading a book about a girl with bipolar II im wondering if I had as I never said the symptoms of my psychiatrist and I thought it was irrelevant. Although I have depression when excited about something for a short period of time its like my depression was never there, I talk too fast, I feel I have bundles of energy and can not remain still and my mind begins to compete with my ideas or thoughts. Please help me? I'm suicidal, but at the same time, I can never die and I will always be here and have great skills that have not been discovered yet.
You have some symptoms of mania, but I have no place to make a diagnosis. All I can say is that in fact may be bipolar, you must discuss this with your psychiatrist.
