First, make sure to self exclude from all possible places both online and in person. If you’re not allowed to make the bets, gambling becomes a whole lot harder.
Make sure to check in here at least once a day. Read other stories, chat with other people and find the support that you need.
Also, look further into why you gamble. You have already started doing this, acknowledging that you enjoy the rush. Consider what your triggers are and this will help you to avoid them or handle them in the future.
I would also recommend talking to your parents. It sounds like they are your support system and will be the greatest help of all for you!
