I'm absolutely dying right now on a bank short. Need advice?

OK, so I screwed up and shorted B of A right before they banned shorting on the financial stocks (no need to comment...I know I made a mistake). I am so tempted just to buy to cover this morning, take the loss, and go back in heavy on a few banking stocks today with the anticipation that bank stocks soar (yes, I'm uming the vote goes through). If I hold on to this and this vote doesn't go through, I will be doing quite well on the short (but I think I'm fooling myself)
