Addiction, withdrawal...dependence, all displayed in gritty detail. It's not pretty, nor pleasant but it is true. The idea of having to hit bottom before you can start over is crap. Too many die before they realize they passed the bottom. Too many suicide with an overdose because they can't take the pain of going through another withdrawal. Addiction is a mental health problem that is totally out of control in this country. While there are some who get lucky and find their way out of the maze with some help, there are far too many that exist day to day before they too end up a statistic. Addicts are notoriously secretive and try to hide their problems and refuse to discuss them.
Sorry, I have too many friends who have lost children, siblings, spouses to addiction. Some are forever heartbroken, ridden with guilt and thinking there must of have been something they should have done better. I don't know the answer, but I do know effective treatment is expensive, hard to get into and no guarantee of success.
