What will happen if forgot to square off shortsell

Today i sold 5000 shares of one company at rs 12.85 , but at the end of the day I forgot to square of my shares.

What will happen now , how much loss will i make .

Need help on this , as my mind is not working.

I received one message saying that you need to tranfer same shares from your friends or relative to adjust or it will go for auction

it will go to auction and your broker will buy back 5000 shares for you.
