If this is your first time into gambling – then just draw a line under it and move on with your life.
You have discovered that you are not able to stop when you are winning but have the urge to keep going. That is the downfall of the problem gambler. The lure of the gamble is greater than any win and money ceases to have any value other than as tokens to carry on gambling with.
You have told your wife what is going on – that’s great. If you feel tempted to try your luck again – ask her to keep your finances for you until this passes. You could try scratching off the 3 figure number on the back of your credit / debit cards so that you cannot use them on-line but can still use them for real life transactions. Ban yourself from gambling sites – google how this can be done in your country or state.
I hope this is a one-off experience for you and yes it has proved expensive – but some of us have lost houses, jobs, partners and good health through gambling. Don’t join the ranks by trying to win back what you have lost. Keep strong.
