Congrats to everyone celebrating a milestone today.
Jsm I'm sorry you have to deal with this.
Try as we might, you can't control your brothers erratic behavior or even the way it impacts on your other siblings - but you can control your reaction to it all.
To me thats key - I have a challenging family - when I stay sober and calm I tend to be more effective and they tend to be more cooperative.
Prayers and best wishes for you, your brother, your sister and a full recovery for her.
