I've been in a similar situation many times, and I know how frustrating it can be. When I get to the point where it sems like I'm getting rags and totally missing the flop, I try to disregard what the cards are. In other words, I try play as though I flopped the nuts and look for good situations to pick up pots that seem to me relatively uncontested.
For example, UTG+1 raises 3x, it's folded around to my in the CO. I look down at 7 9os. Usually this a clear fold, but after countless orbits of missing and getting pushed out, I sometimes deside to call. If the flop comes low, this us a perfect oppritunity to bluff/steal. I can usually safely assume that an UTG+1 raise is anywhere from A10 +, and with a low flop, they most likely missed. This is a good time for a raise/push. Unless he has an overpair or is just hoping to get lucky with overs, they will most likely fold, leaving you with enough chips to finally catch a good hand and make a proper double up. Also, remember, just because you don't look down at paint, dosn't mean you can't play it, even when you are down to 6-10BB. Look for situations, not cards. At least this is what I do. And if you still don't get ahead, there is always another game to play, don't sweat it.
