your post has really touched me. Both my parents were A's. they both died young, tho had quit drinking for the last few years of their lives.
I know you are feeling so sad. Knowing there is nothing you can do, and that your dad is choosing to do nothing, as of yet.
it is almost like you have all been victims of a shipwreck, and all except your dad have decided to climb aboard the liferaft. He chooses to do nothing,just wait to sink, thinking someone surely is going to be there to keep the worst from happening to him. You cant go after him without risking your life, and if you did, he would just fight to get free of your helpful arms.
maybe when everyone stops reaching out(which you all have rightly done), he might see that death is waiting to take him. I hope that he gets a wake up from this.
you are doing all you can- taking care of yourself, and choosing to live a sane life. you are in my thoughts today.
