Hey
Thanks for your post and it made good reading, It’s good that you sound like you have a lot of motivation and you want to stop and I wish you the best of luck.
Just a quick point I would like to make;
You said “I should probably terminate my Neteller and Skrill accounts but decided to leave them, will use them in future not necessarily to gamble but to do online shopping etc”
As you said you probably should close them so you know yourself it would be a good idea, I think you need to close every door which helped/led you to gamble and With this in mind I would close them. It might be a bit of an inconvenience if you use these accounts for shopping but it will be an even bigger inconvenience if it helps you gamble.
Good luck
Tony
