Screwed

I am officially screwed.  I found out today that my bank account itself is being garnished in addition to my paycheck.  So, the $104 paycheck that I received Thursday was not only garnished, but, when deposited into my account, I was garnished $241.79.  How can they more than double my paychecks?!  The only money in the account was already called for!  It was my power bill!  How can they take that?!
