Teenagers relapse back into the drug and alcohol world for several reasons. Parents need to be educated in understanding these reasons so they can learn to talk openly with their teen.
So often we really don't think about our mental health. This is partly because the phrase mental health is connected to mental health disorders and there is still quite a stigma in our society about these types of disorders or illnesses.
The one that comes to my mind is when you watch your teen changing friends, skipping school, unwilling to talk, and withdrawing from what they used to love doing.
