Before you or I judge the person who is still sick and suffering, please read this! I know I didn't choose to become an addict. That never was my dream growing up. However, I do have a choice when it comes to my recovery.
You don't get over an addiction by stopping using. You recover by creating a new life where it is easier to not use. If you don't create a new life, then all the factors that brought you to your addiction will catch up with you again.
