But there's one thing that always remedies the situation: playing music.

What my mom describes happening is her toddler not just slamming his hands on the ivory keys, but trying carefully to play keys in a way that a pianist would.
Since then, I have taught myself to play four different instruments: guitar, piano, bass and drums. I have no idea where this skill came from, but when I hear a song it stays with me forever, and I can immediately apply it to an instrument within five minutes.
And when I do, something magical happens. Playing music takes me away from the worries of my life. It is my escape from reality. Without the constant communication between music and my soul, I'm not sure how else I would deal with my stress and anxiety besides laying in bed all day. And I'm willing to bet Beethoven was not a couch potato.
