The first one to be clear about is A. Is this clearly different from the usual? Also, does this prerson have the associated depressive episodes?

I disagree that only #7 can be considered "destrucive". I think they can all be a bit hard to handle at times. All of these things can be destrucive when taken to extremes as in hypomania. However, I believe E is intended to distinguish from a type 1 episode that is much more severe. Also, I question your use of the word always. I think it is possible there are times when hypomania is not destructive in itself but one may still be bipolar. Usually the precipitious drop into depression from a hypomanic state is what is most hurtful.

Really though, the best thing to do is refer your friend to a doctor for a proper diagnosis.
