Hi Alex and welcome to the site. If you read some of the other stories here you will see you aren’t alone with this problem, you will also see the sort of things that have helped others to stop gambling – hopefully you can apply some of those to your own situation.
Where is it you play poker with your dad? If it is at a casino then why not get self excluded from it? That will remove one temptation as your dad will know you can’t go with him.
There is a lot of gambling around these days – the good news is that there is also a lot of support available to us as well. Have you tried a Gamblers Anonymous meeting?
Use all the support you can, if we could do it on our own then none of us would be here. Keep posting and let us know the positive steps you are taking. What things can you put in place before you next get paid?
