I'm holding this grudge against my dad from a decade ago
Why are you still holding a grudge against him?
If he had been a better dad then maybe I wouldn't be a full-blown alcoholic now.
Your dad needs you to help him through his alcoholism and being resentful towards him doesn't get him the help he needs. Find compassion in yourself for him and be there for him in his time of need.
Me being a full-blown alcoholic is just a phase that I'll grow out of, I don't see a problem.
It's nothing something you just grow out of. I really think you should start going to AA meetings or something.
