Jencita,
Regarding the medications thing.... Strattera works great for one of my kids, made the other one even worse!! I agree with all the earlier posts, you need a good psychiatrist & therapist that will work with you.Keep looking, it makes such a big difference. This is a tough age for difficult child boys, not that any age is easy but you get the teenage thing along with the difficult child thing now.
What about county Mental Health services, would those be an option?
Hang in there.
