Welcome, Beebizzy. I like your name.
It can be hard to accept a bipolar diagnosis. But really, the label does not change anything. Diagnosis or no diagnosis, you are still a person who has gone through episodes of depression, and (according to your loved ones, at least) episodes of hypomania. The label simply helps your pdoc know how to treat you, and allows you to join an excellent community like the bipolar forum of pc! Honestly, this is a great place. We'll be here for you through the highest high and lowest low.
One thing I'd like to ask you: why do you think you would "fake your behavior"? What could you have stood to gain by faking?
Welcome again.
