One of the amazing things about treatment programs is the effect it can have on family relationships. When you are young since you are around your family a lot and live in the same house usually, you can start to take each other for granted very easily. You can begin to annoy each other, argue and fight with each other. Kids can chafe under the strict rules of parents from their view, and parents stress out about what their kids are really up to. Families are complicated and involve a lot of emotions and like any relationship it can get ordinary and rocky and times.
When you are away from your family at a treatment program, over time, the arguments you once had seem trivial. You begin to realize what you really had with them, when you longer have it. This allows the stressful atmosphere that was present at the onset of treatment dissipates and allows a new relationship to form built on a strong foundation of honesty and mutual cooperation.
Many kids who arrive in treatment are very angry at their parents. This fades over time when they realize that perhaps their family has their best interests at heart. This anger eventually disappears, and they realize how much they really love their family. This effect will not happen with local therapy. Sorry but this is just a fact. Parents shouldn't underestimate how much a change can occur in the relationship between family members when a kid is in a treatment program. I've seen it and its powerful stuff, kids who said they hated their parents on day 1, when they get to go home with their parents they are totally changed and telling their parents how much they love them. Its pretty amazing actually.
