Advice needed for preteen

Patricia
My 12 yet old has been getting out of hand for a while now. But his attitude to life is beyond draining to me. He hates everything mainly due to being overwhelmed at school but his teachers say he's brought it on himself by not doing his work. We seem to argue every day and it's literally depressing me (among other stresses like TTC) some say just beat his butt others say get him to church but he goes every Wednesday and Sunday and still lacks faith. The way he talks toys is just rude and I need real answers.
