Good luck FSB. Coincidentally, when I was 24, the exact same thing happened to me. I had a bad, bad week (damn hockey), and had to hit up my parents to pay my local bookie. Like you, they could afford to help me, and it wasn't the end of the world, nor was it 'rock bottom'.
But I never gambled on sports to that same extent again. Like Dante, it is now a hobby for me, which is strange, because I seem to have such an addictive personality regarding other things in my life. Just not sports betting anymore.
I never did the G.A. thing. I didn't really need to back then, as I was broke and had no money for betting anyway. But I imagine that G.A. would/could be something helpful for you.
Again, best of luck, and let us know how things turn out.
