Being an enabler, no matter how well-meaning, prolongs the agony for all concerned. Compassion sometimes must take the form of tough love. Once recovery starts, positive encouragement is a really big deal.
This is true, as was what Bann said about standing alone.
The problem is first recognizing that you are dealing with an addict.
Then seeking help for yourself.
I know a couple who were both "trained to recognize" drug problems, they just didn't recognize that an immediate family member was an addict.
Support groups, forums, books, any form of education helps you learn.
You learn that addicts are great liars, they are great salesmen. Con artists.
While your instinct is to help, you learn you can't force them to stop, to seek help.
You learn that the law is on their side, it protects them.
1. you can't force them into treatment
2. you can't get a peace bond to stop harassment because they are a family member
3. you can't get a protective order unless there is real violance
4. it's hard as hell to evict them from your home. The courts are very sensitive to the lack of services and are not inclined to throw people out onto the street (from a family home).
5. People who are not educated (on addiction and addicts) see your tough love as rather selfish and will often undo by their uninformed acts of compassion, what you are trying to do.
5. Letting the addict hit rock bottom is not easy, it's painful to watch and it can be over a prolonged period.
