Welcome to the forum and well done for making the decision to quit. I take it that you had a long period of abstinence if you blew 12 months worth of savings? Yes, that is what us CGs do, we can never win. All wins end up as even bigger losses. Until we make the decision never to make that first bet. It is the only way to avoid more pain and suffering and a bottomless put if how far we can fall. Have you told your fiancé and self excluded? What did you gamble on?
You will find that you are not alone and the forum is helpful with support from fellow CGS working recovery. Are you getting any support at the moment? I would recommend you try GA or the groups on this forum. Where you are we have all been and understand the suffering it causes. Well done again for making the decision to quit.

Hi James ,
Well done on your honesty –
Buy a gambling blocker for your laptop or phone .
Betfilter or gamblock .
It will mean that even if you are tempted you will have time to think things through

What happened at 8 months that made you want to gamble again?

it’s really tough to find yourself in this place again but you can’t change what has happened, i imagine there is a lot of “what ifs” and “if onlys” constantly spinning around in your head but all you can deal with is today, self excluding is a big positive step.
one thing that was pointed out to me recently when i kept giving up and gambling again and thinking each time that i gave up i was in recovery and be ok this time, i was actually only abstaining from gambling and not taking steps to prevent me from gambling, i was set up to fail and now with that realization i am actually getting the help i need to kick this addiction.

Hope you come back and aren’t continuing to gamble.
