re: Poker & Bankroll Nazi!!
When I lose considerable money - which of course is highly relative to each individual - I usually just write it off as entertainment for the evening. I mean, I'm just playing low stakes, so the most I ever lose and consider as a large loss is maybe $10 - so I just bring a sandwich to lunch the next day and don't eat out at work.
This is my way of justifying my losses and I think it helps me in the wrong. Sometimes it's hard to separate ourselves from the money, even then once it's in the pot it's not longer "ours". So what I do is simply try to find a justifiable raise to excuse my losses, otherwise I'd always be on tilt after a losing session and that's no good.
Maybe the first thing to do is reconsider the stakes your playing at. If you're having an overall winning "career" of poker, than just keep that in mind, and like I do just write off your losses as a fun evening you had to pay for.
