I would say try what you're already considering trying. Tighten up your game, play textbook poker for a while. It's the easiest way to show a profit without having to think so much. Make standard raises, fold to most serious aggression, camp for good hands. If you can do this and show a few winning sessions in a row, even small wins, it may turn your confidence back around and you'll be ready to loosen up a little bit again.

If you find that you want to play a looser game overall later on, might I suggest 6 max? If you're not playing it already, that is. It's the best playground for creative poker. But you still need to understand that sometimes that overpair or two pair is no good. Maybe one thing that you're lacking lately is the ability to make tough laydowns, or see when you should be making a tough laydown. Do you ever notice a kind of sick feeling when someone raises you big on the end, but you think "I've got kings here, the board is jack-high, I'm good" - and you call - and you go broke? That sick feeling is an instinct that maybe you're ignoring a little too often. Go with your gut a little more, even when - especially when - the cards are cold. I'd rather get bluffed out of a medium-sized pot than get broke chasing a huge one.
