Hi laura, well done one getting passed those urges.
It sounds like the financial side of things will soon take care of itself. The help I mentioned on your other thread was the help that the Citizens Advice bureau and otehr places in the UK offer for free. They can help people get things to a manageable position if they are unable to do that on their own, they do that by writing to creditors etc. It sounds though as if you can manage things on your own re the money side of things.
You can get a blocker for your PC, that way you can’t change your mind or look for other sites.
Be careful of having all your money in cash though. Whilst your current “drug of choice” is online gambling once that is removed you might find other forms of gambling more tempting – having a lot of easily accesible cash lying around can be problematic for a compulsive gambler. keep posting.
