This seems to happening alot lately. Can someone please offer some guidance?

The Scenario:

1) I have been patiently waiting for playable hole cards for what seems like hours. I typically start tight and play all pairs, group 4+ hands, and Axs when in position. I will fold weaker holdings to moderate pre-flop raises, but will raise with stronger holdings or if in position. Later in the game, I loosen up and include middle suited connectors, and if the game is loose , any two cards that will give me a black-jack hand of 19 or higher.

2) The flop comes down and I completely miss. Help! What do I do now?
Typically, if I raised preflop, then I will make a continuation bet. Sometimes this works, but most of the time, the stronger players expect me to bet and call me. If someone else raised preflop, then I fold. If someone else bets on the flop, then I fold. Am I completely missing something or am I simply screwed at this point?
