This forum can help you to stop betting, but it can’t recover the money you have lost. The only ways to do this legitimately are to earn it or to sell your own stuff to replace it. Please don’t try and win it back – gambling caused the problem and it will not solve it.
1000 dollars is a lot of money for a student – but it will be a small price to pay to find out that gambling is not for you. Many people lose that sort of money on new ventures and move on – I think that is what you need to do. So please stop gambling now.
If you need help and advice on your finances I suggest you check if your college has a student counselor or finance adviser – seeing them may be the first step. I wish you well.
