Eben - take comfort in the fact that you are that one experience better because of it. Use it as a tool, a learning experience, and you'll have a bit more edge when the time comes again.
I think I've been to the dance at least once and maybe twice. I've landed fish into the high 30# range but I've also had a fish on that made those 30#ers feel small. That feeling was both exhilirating and scared me a bit into trying to approach it with more "training". Working thru the hypotheticals so you may be more prepared next time around....
All that said, if you can' talk about the one that got away, you can't be fishing
