Hi Peter. You're not in an easy situation by any means with your brother. It sounds like his problems are serious, and it's good that he has been seen by a doctor, but six months to wait to see a counselor sounds like a long time. Did the doctor prescribe any medicine? It sounds like it would also be appropriate for your brother to see a psychiatrist, as medication can help during the times when he is getting in trouble and doesn't see it as wrong. Actually, he would need to take the medicine all the time in order to prevent those episodes.

Other than monitoring your brother and making sure that he goes to his appointments, there isn't a lot that yoiu can do. We can't change other people, only support them and help them to change when they are willing to do the work. If he is stealing from you or hurting you, you need to hold him accountable. Don't cover for him. If you brush it off and make it look not so bad, he'll keep doing it and it will keep getting worse until you can't cover it up anymore, and he'll be in much bigger trouble than if you hold him accountable now.
