If it helps, guilt is a nearly universal reaction to the death of a loved one. We all feel guilt when someone dies, although normally it passes fairly quickly. But when someone dies of alcoholism it's much more acute. Keep talking about it ... it will pass. You did everything possible but no one can stop an alcoholic from drinking if they decide to do so. Remember, feelings aren't facts: just because you feel guilty doesn't mean you've done anything wrong. My heart goes out to you, a big hug.
