Hi Kam and welcome, well done on looking for help.
Read the other stories here and you will see a lot that you relate to. You will also see the success stories – what are they doing that you can apply to your own situation?
What barriers can you put in place? What financial accountability can you use?
What support options can you get to? You have started posting here, maybe check out your local Gamblers Anonymous meeting as well.
Your Mum doesn’t believe you? Why should she? There was no reason for my mum to believe me when I finally stopped.
The actions I have listed above though are actions which will not only help yopu stop gambling but also give her cause to maybe think “Maybe he means it this time.”
Keep posting, you can show your mum this site as well, there is a Friends and Family Forum that she might find useful.
Check out the group schedule as well. A group for New Members starts in about 15 minutes, maybe I will see you there.
