You are in a very difficult situation with no easy or great solution. I see from another thread that you are not your mother's only child. Your siblings have as much a responsibility to be involved as you have. Perhaps you live closer to Mom than they do. That does not let them off the hook. They ought to show up and let their mother know that they are concerned. They should be very grateful to you that you have been so responsive to these emergencies involving their mother. My guess is that they probably have not been. It's very unfair to you. Typically, in families, one adult child takes the lion's share of the responsibility. It can wear you out.

A family intervention might be in order. That would involve all your mother's children sitting down with her at the same time to express their concern and urge her to participate in longterm treatment. (Even if they have to travel a long distance to do this.) Your siblings should express to your mother that she is being unfair to you. That may not get your mom to see the light, but it's apt to make a bigger impression than you dealing with this all alone. I agree that an emergency call button would be a very good idea. Your siblings should be checking in with Mom regularly, to lift a little of the weight off of you. Do they provide some attention to her? Loneliness sometimes is a factor driving alcohol abuse.
