Welcome to this board. I can not offer you any specific advice, except to tell you that you will find a wealth of experience from other Moms and Dads here. Please feel free to ask any questions that you have, and I'm sure that there will be someone who will have an answer for you. I have a 13 year old son who is also extremely defiant, and he has to have his own way all the time. I know how difficult it is for you, and you also have to be there for your other children. I am sending you best wishes for better days ahead.
