Mel's Mind Dec 5

Hmm, I am not even sure that if it is really Dec 5, but I think so. I will have to check that and get back. On my mind today is bipolar disorder and behavioral issues. How does a person decide when the line is crossed from behavioral to the actual disorder. Case on point: A 14 year old with bipolar is having school avoidance issues. He went to an intensive outpatient program for three weeks. On week passes and the child is still having the same issues that put him in the outpatient program. He goes to a therapist who recommends 1/2 days at school. Question: Is this a manifestation of his illness or is it a behavioral issues that has nothing to do with the illness? Where is the line and how does one know if it has indeed been crossed?
