sum1else I would like to echo the others here who sympathise with your situation and that I know it is painful seeing someone you love and who apparently loves you continually misunderstanding how their actions affect you.
I am interested in this whole subject, as I have a bad relationship with alcohol and have chosen to forgo it entirely rather than risk it impacting negatively on my loved ones.
My understanding of true alcoholism in the disease sense though is when a person can literally no longer function physically without constantly drinking, and that some of these people appear to live relatively normally until their health fails. I believe there are similarly functioning drug addicts.
I have never been at that stage, but have drunk "regularly" to anaesthatise myself from emotional distress, and it has enabled me to express that distress (inappropriately yes) while feeling as though I wasn't allowed to in "real life". So I choose not to drink now because I have accepted I need to deal with my problems in a healthier way.
(ADs therapy etc).
Some of my issues stem from childhood, some from a horrendous prolonged period of stress following my sons birth 16 years ago. The combination of both has left me with Complex Post Traumatic Stress Disorder.
I am very wary these days of the attitude that people will do almost anything to avoid personal responsibility for their badly managed distress. I was brought up to believe that one should just be able to "pull ones self together", keep calm, carry on, and put others needs first, and for a long time believed that I was a worthless person because I was never happy, despite my perceived advantages.
Even now, although I "know" I can alter my negative thought patterns, "believing" it is a whole can of worms I am still scared to open. If you are programmed to persecute yourself, you repeat those patterns, not because you enjoy it in any sense of the word as you understand it, but because your emotions are warped, you have never experienced true self-esteem, and you fear that experiencing good things when you are not supposed to will be wrong. I can torture myself endlessly into stalemate over this. I used to drink when it got too much. I'd get temporary relief and start the process again. Not good.
Sorry, didn't ant to hijack this but, what I wanted to say is that people are very complex, a product of genes, parenting, environment and culture. Yes, pursuing behaviour that damages both yourself and others without caring about others is selfish, but the "delusion" that it does not means denial, guilt and shame that maybe can't be dealt with.
Sometimes I don't believe I am worth the air that I breathe. I consciously reject these thoughts because I don't want to hurt my family and I am trying to be unselfish, so I have tried to stop my damaging behaviours. I am currently without a true sense of self at 42, and also am aware how self absorbed I sound. The world inside my head is a scary place to be, but my survival instinct is still there and I am lucky that I am going through this now while I have a chance to make things better rather than after years of damage from alcohol or other salves for my "psychiatric injuries".
What I would agree with is that it is right and proper to protect yourself and your family from the stresses that your mother causes, otherwise you are both enabling her and compounding the damage. It is natural to be angry.
I wish you and your family well.
