Dont be a loser! Man up, take a loan, re-deposit and win your money back, never walk away from the table as a loser.
If this happens to me and somehow I lose this amount of money/btc in gambling, although I believe i don't let greed control me but if I loose somehow I'll immediately block that site or anything similar or maybe take a break from Internet. and take it as a lesson a very expensive one though.
