Well done for taking this step. I feel you know you had to but are perhaps having second thoughts about it?
I know when I was gambling it was almost like having an angel and a devil on each shoulder – one saying I should stay away and the other saying – just one more time – I might win! Too often the devil won.
Dealing with the emotions is key and that will be where you need support. Try GA again but if GA is not working for you, see if there is any access to counselling through your GP or Mind or other local organisations. If all else fails the Samaritans will listen to what is going on for you – they are not just there for the suicidal. Post on here and use the group sessions. I hope to hear more from you.
