I think my family is dysfunctional
Is there a reason why you think your family is dysfunctional?
It's due to the neglect and beatings I received as a child
If that is the case I think it's worth cutting those people out of your life because they will continue to drag you down. Once an abuser always an abuser and you deserve better. There is no reason for you to go back into that household.
I'm fine. Don't you dare tell me how to feel or where I should go. I will do what I want.
If you feel like your family is causing you harm then it is okay to move on from them. You shouldn't be around people that make you feel bad. It would be better if you tried to make yourself happy for once.
