Hi VJ and welcome to the forum.
I am sure that reading the other stories here you will be reading a lot you will relate to. You will also be reading the success stories – what are they doing that you can apply to your own situation?
Lizbeth has already given you a good suggestion; many peole who use this site also go to gamblers Anonymous meetings.
How about being honest with your girlfriend. She can then help you by looking after your money maybe? What other things can you put in place that will make it harder for you to place that first next bet?
Keep posting and let us know the positive steps you are taking.
