I do not have any alcoholism in my immediate family.
I do however have two parents who I am pretty sure grew up in alcohol homes.
I have a lot of extended family with alcohol problems.
I have struggled with food stuff since a young age, and I suspect my brother struggles with substances.
I think the tenants of growing up in an alcoholic home can still be in place without any recovery. I think the don't talk, don't feel, don't emote mentality is present though the addiction was not. At least that was my experience.
My problem drinker that got me here grew up in a functional alcoholic home (I don't know that he would name it as alcholic as a result)
