Can an addicted gambler work himself out of that addiction without help from anyone, if yes, is it still addiction?
Others can discuss the rest of the questions but I will dwell on this!
Firstly the thinking that you can escape addiction allow is where you will never get out of it, I always suggest that seeking of help is the most important thing anyone can do and that alone can get you off it! the courage of asking for help only signifies that you are fully ready to receive a method of help that will be offered.
Hence I suggest you should heste to do the necessary by asking for helping hands.
