I have a 17 y/o grandson whom I have had custody of since he was about 3. Mom is still in the picture. He has been in therapy since about 5, Multitude of psychiatric diagnoses including ADHD, bipolar and the latest is ODD. He recently had a hospitalization after he hit his 15 y/o brother in the head with a plastic light saber in anger to the point that it caused him to have staples. He threw his brother's Playstation on the cement, smashing it. Police were called and he had his first psychiatric hospitalization. He makes demands of me continuously. Will not take No for an answer. If I am in bed, and he wants something, he will bang on the walls, call the phone, pound on the doors until I give in. I have had to hide the knives, my purse and anything that he could use of mine. I am tired of being his doormat but on the other hand I am not strong enough to stand up to him. I don't want to get the courts involved. I did this with his mother when she was his age and it cost me $60,000 and ended with her getting pregnant with him. She still has the same behaviors today. I believe that a lot of his behaviors seem like Reactive attachment disorder. He doesn't seem to care that he hurts me. For the last 3 weeks, he has been staying with Mom, but she is ready for him to come home. Supposedly he has been behaving very well and doesn't want to come home. I believe that she is pushing the issue to hurt me. He does need to go back to school. Is there somewhere that I can learn to grow some hair on my chest, to be strong enough to say No and mean it. I don't want him to end up in prison, so he needs to learn that there are consequences for his behavior without the end result being injury to myself, his brother, the pets or damage to my home!
