Usually I will just keep folding (face-down) and try to stay patient. As always, I might still try to
bluff at situational spots here and there (since cards may not matter if I don't plan on getting to showdown anyway), but typically folding is best. Everyone gets card dead some times; what you want to avoid is tilting or blowing off your stack on some forced bluffs. When card dead, the goal is to survive and wait for the better cards again. Being card dead can be annoying at certain spots, but that is a part of the game and it happens to everyone sooner or later.
