I fear this is simply not something I'm able to do. Any effort to "work through" such things would simply make me more angry about the gap. Like being driven mad by a word you can't remember or the name of a piece of classical music where you don't know who composed it. It drives you crazy, and every time you're reminded of it, it drives you crazy all over again.I just work through any of my issues during play as I attempt using house rules that just never stick.
Part of this, of course, is that I would never willingly DM 5e. The only system I know how to run that I would be less willing to actually do so is 3.X/PF1e, and the gap between them isn't very big. (Naturally, I'd also never run MYFAROG or FATAL, but that's because they're horrendously offensive and garbage rulesets, whereas no edition of D&D or PF has ever been even remotely that offensive.)
So since I'd never run it myself, I'm stuck choosing between playing and not playing. Thankfully, I have a friendly and supportive 5e DM at present who has, if anything, been more accommodating than he really needed to be.
