My gf of 4 years has really bad anxiety and panic attacks, and it has gotten a lot worse recently. She's been having panic attacks every night and tells me she has bad anxiety though out the day. Has already been diagnosed and is prescribed anxiety medication that she says doesn't work at all. We live decently far away now so we only hang out about two times a week and its usually at my house, but tonight I was over at her place and found that she had a couple hundred empty whiteclaws (hard seltzers) under her bed. We got into a huge fight about it so I not sure exactly how many, but there was an insane amount. And I know she has drunk all of them in less than two month, because I helped her put her new bed together that they were under. Said she has to drink or her anxiety and panic attacks are so bad she can't sleep at all. I feel like this would already be pretty serious for most people. But she's small, is predisposed to alcoholism, and pancreas problems that put her in the hospital for almost 3 weeks last year with a feeding tube and claimed she had barely been drinking at the time. Was told by all the doctors she could maybe have a few alcoholic drinks a year for the rest of her life or risk ending up back in the hospital. Maybe this is the wrong subreddit, but the main root of her problem is anxiety and panics attacks so thought I'd try here. I really have no idea what to do, I'm extremely worried about her. She was already drunk tonight and just kept insisting that nothing could ever help her anxiety and she'd always be like this. I just know if she continues like this she'll end up back in the hospital very quickly and probably if she hasn't already develop a dependency on alcohol. I just about her so much and just can't let her do this to herself. Any advice is very appreciated.

sorry for bad grammar and one long winded paragraph, I'm super tired
