Congrats Astro on getting offered a temporary job. As you said, it will be great to have something you can channel your energy towards.
One thing that might be worth considering is having someone else handle your money at least in the short term. As Charles has helped me understand, even if you are doing this, you are not handing over responsibility for your money, you still control your finances and decide where it is spent, but anytime you want to use that money for something, it has to go through that other person thus reducing the chances that you have access to funds for gambling.
