What you're describing, Razzle, is something of what I experience. Extreme, drastic mood swings that only last hours or days, sometimes even minutes. Suicidal, irritable, angry, terrified, numb, sometimes happy gets thrown in there. I go through periods where I'm highly active, thoughts racing, much more creative, don't need sleep - as opposed to the periods where I can hardly think, am extremely lethargic, and want to sleep all the time. but I don't ever talk faster, don't usually feel super great... idk. I'm being treated for depression but I'm nervous that I'm bipolar II.
