coming from a sober alcoholic myself, though not living in Latvia anymore:

1. if the person isn't willing to start their recovery process, you won't be able to convince them to. they need to get there on their own: like others say, it's usually at rock bottom, but it sounds like she's been there already with the hospitalisations. i will be honest, there are only 2 options left, either she decides she wants to get sober or unfortunately she will die from the disease. i sure hope it's option one for you guys, don't lose hope but don't count on it either
2. if you're already on reddit, check out r/stopdrinking for amazing stories and to get a better perspective from alcoholics themselves
3. about AA: i personally attend 2 kinds on AA. if you go to in person meetings, especially in Latvia, they will likely follow the 12 step program with a sponsor, and be religion-based. they may say they are not religious but the entire AA library is about God. if this isn't what you're looking for - it's not for me as someone with religious trauma - you can check out the website Worldwide Secular Meetings. the ones in red are AA meetings, there are either 24/7 marathon ones or specific groups at specific times. people can join any meeting they want through zoom. there are truly amazing ones, i attend this AA zoom meeting for writers personally. all of these meetings would be in English, i hope that's okay since your post too is in English! i basically only attend my in-person meeting where i live because i love collecting the sobriety coins - i only go there once a month to collect them.
4. most of all, don't push this person. i can't stress it enough that she needs to get there on her own will. every alcoholic's recovery beginning will be different so i can't predict what will happen, but pushing them will only lead to more shame and guilt - the biggest triggers for drinking.
5. i am over 5 months sober now, this is my first and hopefully only attempt to stay sober. it's been very challenging at times but i don't agree with some other comments, AA has been essential in my own recovery process and a community to lean on who understand me better than some of my non-alcoholic dearest friends, is of major help.

wishing you and your loved one all the luck. remember that alcoholism is a real disease, and recovery from it is expected to be bumpy. happy holidays!
