Hi Life and welcome to the site. Well done on starting your own thread here.
First of all from your posts I would say that I don’t think you are an unlucky gambler. You are a Compulsive gambler and there is a big difference.
It will help if you come to that realization yourself of course, check out the GA website and answer the 20 questions they have there and see what you think.
Read the other stories here, you will see a lot that you relate to. You will also see the success stories, what are they doing that you can apply to your own situation?
How about getting yourself banned from your local/usual bookies?
It also sounds like you have unaccountable, easy access to quite a lot of money. How can you limit that access? How can you make yourself accountable so that you can’t gamble secretly, can’t just pop up to the bank as soon as you get an urge?
Keep posting, let us know how you do with those GA questions and also let us know about the positive steps you can now take to make it harder to place your next bet.
