Sad but true but I really do regret it.
I did learn from it though and since then, when exhaustion sets in, I know from personal experience that it's often not the best time to make important decisions. Nowadays, when I'm having an exhaustion day or any other 'down' day, I find a spot, erect my tent, get comfortable and just sleep, rest and blank off and wait for morning! I've found by doing this I'm less likely to give in to negative thoughts or to make stupid moves which I might regret later.
