I am sorry for bad things happening in your life but bad things happen to all of us. You need to change your life and it is in your hands otherwise you will always suffer.

It may be a good thing that your father has revealed his addiction. I am sure a lot of your issues arose from his substance abuse in ways you were not aware of so yes of course THAT is your "reason."

Focus on protecting and taking care of yourself first...you deserve good things

All the best
