I've asked this a bunch of times just to figure out of I am bipolar myself or if I'm just a little emotional. Here's my family history with it:
Grandmother, Uncle and Aunt on my mom's side, and my mom. My father. My brother, and 4 cousins on my mom's side all suffer from bipolar disorder and/or manic depressive disorder.
Regardless of what diagnosis you want to attach to yourself or have had attached to you, don't let it define you and surround yourself with people and things that make you happy. Also, daily postive affirmations help a ton. Nobody is in control of your happiness but yourself.
Good luck
