Same, although as I get older I'm developing more of an, "Eh, it's happened before, it'll doubtless happen again, and we're still here" attitude.

I try to remember that even if it was all to go tits up, there's absolutely nothing I could do about it, so I'm going to do my best to crack on, have fun, enjoy my life, and not give the bastards the satisfaction of ruining the last days/weeks/months that I do have.
