Inn to keep your kid completely grounded from anyone

We have full custody now.I thought it would fun but I am so miserable and feel like ALL I do is yell all day at everyone.Because he needs more discipline.You can never have too much discipline.My life is miserable and no picnic so why should he be happy.Then he is calling them and talking on the online for hours. I want to keep my bf son isolated from everyone so he will like me best and act better.He wants to talk to me which is discouraged. I only want to hear yes ma'am and no ma'am.He keeps locking himself in his room and refuses to talk to me and has to see a shrink now. He told the shrink he hates my bf and I because all we do is yell and punish him. We have to be as cold harsh and demanding as fuck to raise a good kid.I also want relatives to give us lots of money without seeing the kids or talking them when they come over. But they butt in and spoil them and talk nicely to them which is so annoying. The more insulting I am to the relatives and the more I keep him away from his grandparents aunts and uncles. The more he hates us and likes them and doesn't understand why he is being punished.
