I was the same with mybrokenleg.com! When my leg was shattered and I couldn't move for months, had to have ops etc, they were the only people that could understand what I was going through. One of them, Mark, is a Facebook friend and barely a day passes without us communicating. He's in California so we've never spoken or met either......
Perhaps one day we'll meet, we're hardly on opposite sides of the world after all......
