What is up with my step dad?

So if your trying to get the point across, do something stupid. Something suicidal but that you dont wont hurt you to the point of death. They will then realize there doing somethign wrong and that you need to get actaul help for it. They will deff start listening to you then. And your step dad just seems like a jerk. Maybe hes ashamed of the fact that your brother is mentally ill and he doesnt want to have two step kids like that.
