Good to hear that you have made the decision to stop gambling and have taken some steps – like admitting you have a problem both to us and to yourself – and that you have blocked yourself from some sites. It will not be an easy journey as many on here will tell you. It would be well to block yourself from the other outlets as soon as you can whilst your willpower is still strong.
Can you get good support for yourself in these early days? You can contact one-to-one here -or there may be professional or self-help groups locally. Do you get support for you alcohol problem? Maybe the same people can advise on gambling …
Other things to do are to keep yourself as busy as possible with non-gambling activities and minimise any money you have access to. No time and no money means no bets!
I hope to see you post again soon. Go well.
