An addiction is when a person’s body is dependent on something. It’s extremely hard to stop; most people can’t without a 12 step program.
Your father will not admit to his problem and stop unless you help him. Don’t be an enabler. Don’t let him continue his addiction. Do anything you can; make sure that he has no access to his finances, tell him that you need money etc.
I’m sure that if you tell your principal or teacher, then it won’t be on the news. However, if you leave him be, he will probable go bankrupt, or worse and his name will be besmirched.
I beg you, please, tell someone. You can. Choose life! ????? ?????.
Your father needs your help. Secretly, he wishes that someone will help him. It’s up to you. DO IT! DON’T SAY YOU CAN’T!
