I can't say anything, about six months I had almost the exact same thing happen except it took my monitors with it. The only difference was that I ended up being the cushion between everything and the wall because I caused the problem while on the back side - ow! 
When they say you should spread your monitors so the sounds hits your evenly, I don't think that's what they quite meant
Must admit, I always knew the balance, was, well, dodgey. I bought two sony bookshelf speakers, removed all the bracing between the desk and the upper shelf, and set the shelf back on the two speakers. The intention was to use them for mono listening, but they were never good enough. But it was never screwed back down. Now, the speakers are bolted to the desk, and the shelf bolted to the speakers.
But to sacrifice yourself. I'm impressed
