I have just posted you the formal welcome message. I hope now you will also get replies from other members who will offer advice, along with emotional support and encourage you to move to a gambling-free life.
You say you have tried to stop on your own for 3 years without success. I think it is very difficult to get free on your own, so I hope you will now make good use of this site – the groups, the helpline and this forum – to gain the support to make your new life possible.
Of course, the biggest part of this is your own determination to stop gambling. Once you are in that frame of mind and have support, you have much to look forward to.
Cast your mind to other things in life, too, that give you some satisfaction and start to build a way of life that has enjoyment in it that has nothing to do with gambling.
I trust you will soon hear from others, too, and I wish you well on your journey.
Monique
