Season change! It happens to me with the weather changing and that damn time shift, more light and longer days. Happens in the fall but, instead of being mostly happy I'm going up and down 'til I'm in my winter hibernation mode ie depressed. Also, if you're skipping meds you might get a bit silly or down.

Oh and are you certain your coworkers were not whispering about you? Gossip is rampant in the workplace. Just because you're paranoid doesn't mean they're not after you.

Lately I like cycling so, I don't know how or why to stop it. I suppose the meds are to do that but, meds just seem to lessen the intensity, perhaps I could try others but, like I said I enjoy it often enough then again, looking at my mood chart I'm going between a little sad and euphoric as hell right now.
