Lexapro and all antidepressants can actually make kids worse--more aggressive, angrier, irrational, even psychotic. My daughter pulled a knife of herself while on Prozac. These are NOT mood stabilizers. I've taken the gamut of antidepressants and the wrong one can mess you up--you must be extremely careful. If it's the Lexapro making him worse, no counseling will help him. And you do need to wean slowly off of it if you decide to remove the medication. Also, if he is using illegal drugs or drinking, no prescription drugs will help. I'm not sure what's wrong with him--is he a drug abuser? If so, I wouldn't put him on anything else to add to his frazzled state of mind (this includes drinking). Looking at your son's diagnosis, in my opinion somebody missed the boat. If he's planning killings, I would say he's got much more wrong with him than ADD/ODD. A re-evaluation and surprise drug test may be in order. At least, that's what I'd do.
