ask his therapist for a comprehensive psychological evaluation to rule out other mental disorders and also contact your family physicial to rule out any possible physical health problems. Also know 12 is the age both male and female children go through mood swings and so on due to hormonal imbalance of puberty. like a friend frequently tells me one munute she wants to hug the teens she has and the next she wants to attach cement blocks to their feet and drop them off the nearest pier because from moment to moment she doesn't know how to react to their moods so she just sits back and says "I'm here when you are ready, otherwise I'm going on with my day, thank you for flying friendly hormonal skys." The kids have actually started recognizing their moodyness with this same wittyness by letting people know they "need to back off while they come in for an emergency landing" It's so comical from my end to watch this playing out among the mom and two teens because they do it so well. One day the mom saw one teen having a rough time and it was only the beginning of the day so while the teen was busy crabbing and fussing about school and what to wear and who's who of the teen age get me today crowd she made the teen a "fly the friendly skys" lunch complete with a bag of peanuts (and a couple packages of gum and a borderline off color joke to share with friends) and slipped it into the teens back pack knowing the teen wouldn't have time to look in the back pack until his first class. The teen came home with a smile and hugged her for making his day with the lunch and making it easier by letting him know she understood teen pressure of fitting in with the gum.

What I've learned from her is you just take it one day at a time and use as much humor as possible to diffuse situations.
