My birth-mother had lots of health issues and one was alcohol. Before she passed she was on a ton of medication and was walking with a cane. The year before she passed away I asked her to come live with me and to get away from all the things she was around. I never knew her that well to begin with but I thought perhaps I can at least help her.
She made up a ton of excuses not to go with me and I realized that there's nothing much I can do. But I tried several times. When she passed it hurt but that was years ago. I've gotten over it since then.
I think at times we can only do whats in our capacity and then let other things go. I still wonder if I could've done something more for my mother and she might be alive. Then again it wouldn't have mattered, some people are so set in their ways.
