Should i move in with my dad? PLEASE HELP. PLEASE. (sorry this is so long)?

If that is where you are most happiest,then why not live with your dad?a big house isnt everything in life,and surely money means nothing compared to being happy and confident in a much happier and less violent enviroment. If you really want to live with your dad,tell him what is happening to you both and see if it is possible to go live with him. You dont need to live like this. You know it will be better for both you and your sister
