I sense that you are well on your way to recovery. In tragtds to the money your dad owes you I would consider it lost money. I wouldn’t even bother trying to get him to pay it. It will only bring more unhappiness when he doesn’t, I suppose it will be a hard lesson but one you have learned.
You are still very young to put this behind you. Seeing a counselor will help you sort your feelings out. Yet return to this site as often as you can for more support. Go back and read other thread as from years ago .
Wishing you all the best.
