I am at my wits end with my son. He has been on methylphenidate for about a year and a half now for adhd and it apparently makes a big difference at school. At home is another story. By the time he gets home his medications are wearing off and it is a nightmare. He'll kick walls, throw things, scream at the top of his lungs, threaten to destroy the house, raise his hands to me in a threatening manner, say he hates life and he wouldn't care if something bad happened to me. If I ask him to do something he'll say he's not doing that until I be nice or until I do something for him, he refuses to clean his room, It's a fight to get him in the shower. It's impossible. I don't know what to do anymore. I don't know if maybe the ritalin may be cause the increase in aggression (it seems to get worse with does increase) or if he's just getting worse as he gets older. It's just me, his dad isn't really in the picture so there's no break and the stress is eating me alive. Any suggestions would be great.
