Yes its happened to me ALOT

This has totally never happened to me ever, at all. What is wrong with you.

Huh, wonder what the thought was...

Sudden Depression strikes again!

I used to has irrational ones that reduced me to tears.

Every Single Day in My Entire Life.

One of these days, the Universe will run out of ammunition, or imagination, and have nothing left to throw at me. When that day comes, I will finally have a good day, free of depression and stuff.

...And the day after, a bus will fall out of the sky from nowhere and land on me. ^_^;;

As soon as the world stops throwing stuff at you, you make up your own problems, just out of habit. Believe me, I'm kind of an expert there.

Happens all the time. Sometimes happens in reverse....I should be gloomy and down, but get a stray thought and suddenly, inappropriately, burst out laughing....

if you read the comic in reverse its much more enjoyable :)

More common for me is getting angry thoughts. Y'know, remembering people who've wronged you in the past and gotten away with it, and would gladly do so again if given the chance? (*cough* 990 Dovercourt Rd. *cough*)

There are certain pieces of music that will make me sad, no matter how I felt before. The last movement of Mahler's 9th symphony is a perfect example. It's incredibly beautiful, slow, and tear-jerking. And it's primarily in a major key - adding so much bittersweetness to it! It's a musical eulogy for his 4-year daughter who was lost to scarlet fever.

Yup.
