I am so sorry to hear this. Unfortunately (or fortunately in your case) I can relate.

I have a son that sounds very much like your brother. My son was intimidating, abusive, disrespectful, manipulating, etc. etc.

After every conceivable doctor, therapist, program, medicine, court (in some cases), etc. nothing worked. In fact I think it emboldened him to get even more brazen as time passed.

When he was 19 I said enough is enough and threw him out. He is having his struggles but this is the bed he made. He had a billion chances to get his act together and make things right but that simply did not interest him. He's my son and I love him but I have a wife and daughter to protect. He's 23-years-old now and he better start figuring things out on his own.

Should your family throw your brother out? That's a you decision. I simply wish you and your family the best. Nobody deserves this.
