Child for Sale...Cheap

I am at my wits end. Matthew has become insanely destructive in the last 2 days. Breaking toys, tearing apart notepads, drawing on his bed with markers, throwing food on the floor. Tonight we found one of the angels I inherited from my Grandmother torn apart in his bed. Why does he do this? I have given up on conventional methods such as time outs...he sits there and then goes right back to his devilish ways. I tried our states Grow with me program and their idea of help was to refer me to kindermusic and library programs. This doesn't help with his issues. I am beginning to wonder if he has ADHD. Tomorrow we will start calling a list of child psychologists we were given. I have had it, I am ready to walk away right now. I love him, but good God is he trying my last nerve.
