I agree with everything so far. You are playing much too tight and (it seems) giving up much too early. What's interesting is that you know this, and are adequately bankrolled for your limit, but are still playing scared. While studying Small Stakes Hold'Em is an excellent start, I also suggest The Psychology of Poker by Al Schoonmaker. It helps you get a handle on what type of player you are and why, and how you can work out your particular weaknesses.
