Nothing life or death, but I attempted to do a 5 day expedition across north yorkshire.
On the first day I broke my thumb in two places in the morning when I fell over (I won't go into details but my friend was laughing

) but we decided to carry on without getting any medical attention. I just wraped a bandage around it and carried on (which I later regret, my thumb causes me problems ever since).
And with only a one man tarp between 2 people, no rollmat, and a small 1-2 season sleeping bag. Needless to say it rained heavy practically none stop. My water proofs was no longer being water proof after the first day, all my clothes was soaked through, I didn't have a warm meal or hot drink for the entire expedition.
Needless to say, after the 5th day when we arrived at the end, both of us was suffering from hypothermia, and nearly was hospitalised by that alone, both of us had trench foot, my friends was the worse case the doctors had ever seen. Dehydration was pretty bad aswell, since us feeling all cold and miserable, we didn't drink enough water. I think only about 2-3ltrs for 5 days of solid walking so that made us feel pretty bad. I got a metal rod as thick as pencil led stuck about a couple of inchs into my thigh one night when walking in the dark, but since it didnt peice my trousers because it was blunt I couldnt pull it out by my self my friend had to give it a really hard tug. My trousers was both badly torn at the knees where I fell on some rocks, taking alot of skin with it causing some deep cuts that took a year or two for the scares to heal. And a load of other minor injuries.
But the main thing that I found the hardest was sleep deprevation, we found it impossible to sleep. Near the end I was beginning to halucinate and act all trance like while my friend kept crashing and blacking out while we was trying to build a shelter one night.
We both looked like an absolute mess when we finaly got back to civilisation. But we did the entire expedition of 120 miles on time.
It was such a hard lesson for bushcrafting beginners, most of it was entirely avoidable with the right experience and understanding. But you can't say we didn't learn ALOT from it. Ray Mear's TV shows never really helped us when it came to it ;-)
Oh and 2 years ago I was nearly caught up in a car bomb in Sri-lanker when it detonated 50 meters ahead on a street I was walking. But that's not really a bushcraft survival story.
