As a daughter of 2 alcoholics I am reading with interest. My dad was a functioning alcoholic, he never drank until everything he needed done for the day was done then would easily drink 3 bottles of wine but was always silly and funny.
My mum was the opposite at her worst would drink vodka for breakfast, she was neglectful and aggressive. I am perhaps lucky that I am young enough to not remember the worst of it but my 2 older sisters do. They have both had their own struggles with addiction, depression etc.
My mum stopped when I was 7 and started again when I was around 15. She stopped again when she went into rehab after she crashed her car with me in (whilst I was pregnant) she has been 9 years sober now.
She cannot drink a drop, no social drinking it is very much all or nothing. No alcohol allowed in her house but is OK with people drinking when out at dinner etc.
My sisters have mixed feelings towards mum. I think they equal.parts love her and loath her for the alcoholic years and have so many things they can't forgive.
I however am incredibly proud of her for turning her life around. She hit a proper rock bottom but now has a great job, a nice partner etc. However we don't have a typical child/parent relationship. I would say we are more like siblings or friends. In that I've had to look after her as much as she has had to look after me and she is not my first port of call in a crisis or when I need advice and it took me a very very long time to trust her with my children.
I have my own bad relationship with alcohol. I grew up with drinking every day being normal as did my DP so we sometimes have to check ourselves (especially over lockdown) over whether we should really be opening a bottle of wine on a Tuesday.
I wish you all the luck in rehab. I hope it works out for you. I wish SS would have done more when we were children, because our dad could function we were left to it and the damage to my sisters especially has been life changing damage.
