I don't have any real short term solutions. Do you have a counselor? If you do have you told them that you are afraid and fear for yours and sons life because of his threats and actions like throwing the ball and scratching himself? If you have told them them you can go to the court for protection and take a letter from counselor to the court with you. Have you filed for divorce? Do you have any temporary orders in place? If you file a complaint there will be a hearing. It is possible to have language added to the divorce filing to protect you and son. this could be as simple as him agreeing to stay away from both of you.
