My version of rapid cycling:

8:00 am out on the patio drinking coffee life is beautiful.
9:00 am if an asteroid destroyed the earth I wouldn't care.
10:00 am oh wow my new painting is so beautiful
11:00 am oh my God my painting is so ugly I should be jailed
Noon: I'm hungry but I can't decide what to eat.
1:00 pm I decide to become a libertarian
2:00 pm I check Facebook and declare that the entire world is insane.
3:00 pm I decide the leader of the world health organization is the antichrist.
4:00 I decide to clean out my closet because I have to many clothes.
5:00 pm I cry because I don't have anything to wear.
6:00 pm eat dinner but feel guilty because I'm gaining weight
7:00 pm weigh myself and discover I've actually lost weight
8:00 pm decide that life is just not worth living it's all a masquerade.
9:00 pm decide that I simply must go to Nepal before I die and surf travel plans.
10:00 pm go to bed and ponder my exhistance.
