Help! I have too many good RBs! What should I do?

I know this may sound unbelievable, but I have the following running backs on one of my fantasy teams: Peyton Hillis, Adrian Peterson, Ahmad Bradshaw, Matt Forte, and Jamaal Charles. I know you must be thinking "Wow! What a lucky guy!" but no, it sucks. I have no idea who to start every week. Who do you think I should start this week? And if you are thinking "Trade one or two of them, stupid." My response is: NOBODY IN MY LEAGUE FREAKING DOES ANYTHING!!! I've offered a trade to just about everybody and they all just let it expire. I'm the only one who makes any moves and every week, most teams have somebody on their roster who is on a bye week. I need help at other positions desperately, especially WR, but there's nobody available as a free agent. What should I do and who should I start? :(
