I wish I could say something that could make it all better for you. Unfortunately, and I think you know this, it is impossible to change someone else especially if they are all in denial. The only thing you can do is to go to Al-Anon. You can't help anyone else but you can help yourself. And, yes, I would be more worried about your daughter. Once again, you can only pray and trust God's will for her. If she were willing to attend AlAnon with you, well....that would be great, wouldn't it?
It is a family disease and it definitely destroys more families than any other disease that I know of. I will pray for you because I can't imagine being in a family of addicts and being the only non-addict. Being an addict, I can only tell you that each of your family members will have to come to that moment of clarity when they realize there is a problem and there has to be a better way. As for any addict, some will and some won't ever want a solution to their problem and there is nothing anyone can do.
I know I am not telling you anything you don't know but just trying to support You and hope that you will do the only thing you can: pray and get to Al-Anon. If you want to just share anything, you can go to my site at Bella (12 Step Recovery) and you can email me personally. I also have someone that you might want to email who I kind of believe is my "expert" in Al-Anon but I would have to give you her email privately.
My prayers are with you.
