Hi LFoste,
Welcome to the Forum.
Made me so sad reading your story. Your Mum is obviously very Ill from the alcohol, it definitely changes people and not always for the better.
The Icarus Trust post on here sometimes and you can talk to them, and I’m sure there are other places that you can ring. AA do have meetings for families of alcoholics, you would have to look to see if they have any in your area. What about speaking to your Mums Doctor?
Be there for your Dad and hopefully you can both get the help that you need for your Mum, I feel for you both.
Keep in touch on here, take care.
