When I was first trying to stop – I remember those voices in my head. One saying “go on – you could “just” do a 10 … you can manage that, if you lose it don’t chase, you can walk away.”
The other saying, “don’t be stupid. You know it won’t stop at 10 – and you will regret it.”
I often gave into the first voice and then agree with the second, (when I had lost 100 or more.)
Later I got to recognise those voices and when I heard the first one try and needle me – I knew I needed to close it down, so chose to do something else to take my mind off things – or I called someone for a chat.
Don’t be angry at yourself, be caring of yourself instead. You have a bad behaviour (gambling) that doesn’t make you a bad person, or a weak one for that matter. Get good support around you.
Finding out the root cause of your gambling is worth doing, but I think in the early stages of stopping, focusing on measures that will keep you stopped is the key. Strengthen your barriers, keep your personal finances to a minimum (hand over to your partner if possible) and find alternatives to keep your mind off things. Later looking at root causes through counselling can be helpful, but I would go down the counselling route as there may be some difficult emotional stuff to deal with and you will need support. I wish you well.
