When it was everything for you then why you risk that money ? Before losing you haven't realized about your everything ? Why not we assume that you are now lying just to get refund.

Refunding you will be setting wrong example for gamblers here after. If any gambler will face losses then he will come and blackmail that he will commit suicide if not getting back his money.

Moreover by starting playing with them, you agreed to their tos. So, no court will be favorable for you. Be calm and move on. If possible, quit gambling.
