Auditory Hallucinations and Memory Loss in Alcohol Use Disorder - Psychiatry

Auditory hallucinations, amnesia, agitation?

---

My sister came home on the night of April 18 and kept scrolling through Facebook, suddenly talking to herself, wondering if the news was about her, and continuously checking comments to see if they were mentioning her.
Normally, at that time, she would have gone to sleep immediately, let alone scrolling through Facebook for over an hour.
When I casually mentioned, "Aren't you going to sleep?" she turned off her phone and went to bed.
She is now about 27 years old and has had a drinking habit since her teenage years, drinking more heavily as she got older, consuming over ten bottles a day.
Regardless of the time or situation, she insists on drinking beer, even while working on construction sites, where she would drink all day and often consume energy drinks.
When she runs out of alcohol, she goes for rice wine.
On April 18, she woke up after only three hours of sleep and asked me to accompany her to the emergency room.
The nurse there told her to wait for the morning clinic.
I advised her to drink some hot milk and have breakfast at home, and she obediently followed my suggestion.
Later, my mom took her to register, but when the doctor asked her questions, she was hesitant and unable to articulate her thoughts.
Even after the doctor repeated the same questions several times, she would respond with confusion, saying, "Huh? What?" and seemed completely distracted.
Tests revealed she had high blood pressure and possibly a slight tendency towards diabetes.
My sister is quite overweight.
After I went to class, I was unaware of her condition after she was discharged and returned home.
By 10 PM, when I got home, she seemed normal at first, but shortly after my mom left the house, she suddenly acted strangely, staring at the TV without actually watching it.
I noticed she was almost finished with two large bottles of mineral water.
When I asked her if she knew how much water she had drunk, she said she knew, "Three cups," unaware of how much she had consumed.
She kept telling me she heard voices outside the window, as if someone was talking and threatening her, wondering why they didn't come in to confront her.
Suddenly, she broke down in tears in the living room.
When I asked her what was wrong, she said she was afraid to say anything.
She cried continuously, and after comforting her, she revealed that a certain relative had touched her when she was younger (the relative had just left minutes before she mentioned this), which she believed contributed to her becoming more masculine and led her to continuously drink alcohol (my sister identifies as a masculine lesbian).
She was in a state of emotional collapse, her gaze darting left and right, and she would suddenly talk to herself, asking where her phone was and denying stealing anything, saying, "What? I don't know what to say." When I pressed the remote control, she even asked if I could record her (I wasn't recording at the time).
Overall, she was acting very strangely, insisting she could hear people talking about her.
Since her recent breakup, she has been drinking heavily, fixating on whether her friends were talking about her and who it was.
Moreover, the places she goes to drink often have her ex-girlfriend's friends, which triggers her.
My sister feels that everyone is talking about her and misunderstanding her, leading her to drink more and obsessively think about it.
On the night of April 18, she mentioned where she had been, but when I asked her on the night of April 19 if she remembered where she had come back from, she said she didn't know and had no recollection of it.
Honestly, I am very worried that this could indicate a serious problem.
She even asked me if she was dying and has become very compliant, following my instructions about what to eat and drink, suggesting that she is scared herself.
