Hi and welcome.
I’m sorry for the situation you’re in because of alcohol. As suggested above Friends and Family Forum on this site has much help from understanding.
Al Anon meetings in your area have great face to face meetings that discuss recovery from the pains inflicted by alcoholic family members. With either of these you may not like all you hear, try to remember some of the members have been helping for many years and it works if we work it.
BE WELL
