I think you should contact Child Protective Services because your parents are abusing your child and traumatizing his psyche. Because of this, he can face serious health problems in the future. Children are very fragile, and their psychological health is like plasticine; it is just being formed. I still do not have children, but I help children in need. On this site https://fosterplus.org, I learned a lot about how to take care of children. I am sure they will be able to help you; moreover, you will learn a lot about support for children.
