I once broke someone else's arm, and that made me depressed for a couple months.
I imagine breaking your own arm would only be worse, so Ivan has my sympathy.
Feel better, and stop breaking arms. 
TRIGGERED. Warning: Mild Gore.
I skated growing up and watched people break their arms on two different occasions:
---
Once, on my funbox in my driveway. The neighbor jumped the box, leaned too far back, landed on the downslope of the far side of the box, put his hand down. Screamed, got up, and looked at me, terror in his eyes. I looked down. His hand was all floppy. He looked after me, he went pale, looked back up at me and said, "Do you think I broke it?"
"Yeah, dude, you broke it. You should go to the hospital."
He ran up to his house next door. He was back and skating in a week, with a cast this time.

Second time, skate park, indoors, two stories, old foundry. HUGE ramps, mini ramps, wood on cement. The ramps were very large downstairs at this place, upstairs were rooms with all walls covered in mini-ramps of varying heights. I brought both my board and skates, 'cause, let's face it, big ramps are way easier on blades than a board.
I was getting ready for my line, when this dude comes gliding up on a board, and at the peak of his jump, gravity seemed to take hold quicker than he expected. Hand down, again, no wrist pads. Board slips, he fell backwards, and then an audible 'CRACK'. This time, the break was mid-lower arm, and he was holding close to his elbow, his whole lower right arm going the completely wrong direction. He was running around in circles, screaming.
"Call 911!" I screamed.
"No, I got this. 911 is $1000, I'll drive him."
One of my first lessons in economics of rural living in Tennessee.

So yeah, feel better Ivan! I'm definitely sympathetic.
