Did I just get scared here and play this weakly?

[Sidekick]

Table has been running a little under 30% seeing the flop (I know it stinks, but it was the only full ring table open at this level) and the average pot for the table is about $4.

Reads: No one at this table that I have any notes on (where do all these new players keep coming from?) and no reads on anyone as this is my first time around the table.

I feel like I played this hand terribly, but the board seemed scary to me. So I'm not sure if I was sensible or just scared. All comments are greatly appreciated.
