I think this happens to us all... and we all react pretty much the same way
For me thou, aftwer the rage subsides and I find myself reworking aaaaallllll the stuff I've already done, I've noticed that somehow the second time turns out better than the first, I suppose this is because memory is still fresh and I get to improve/polish those little parts I wasn't very happy with but had already done so would not get too deep/back into it. So, in a way, crashing is not always too bad a thing to happen.
Cheers to crashing and buying more ram for Photoshop to devour! :raises the mug:
