Bryon, STOP BUYING.
You own enough already and your losses are big enough. I know how you feel but your problems are bigger than just your average price at this point. Trust me on this one. I have first hand experience here - I'm down on GDN far more than you are.
PS. I am not a broker or financial advisor, and as such I am in no way qualified to offer such advice...
Cheers,
