<human>: Condense the text into a few key points

A little backstory: I've known her several years now, since we started university. Back then she also could drink quite heavily but it didn't seem problematic, she had her life in control. 

After a fairly long time (2-3 years) you could notice her grades were dropping, she was skipping a lot of classes, missing exams, failing to study - resulted in a few extra years of university. She started having fallouts with her friends and with time many others just distanced themselves from her citing no reason. From what I'm hearing several of her friends brought it up to her and tried to help but she became aggressively defensive - this resulted in them too distancing themselves. 

She gained weight and sort of resigned to accepting her now obvious problem. I think that was the most upsetting part, that she'd talk about being an alcoholic like it was a cool thing, like it was a rare talent. She hangs around enablers only, and I'm fairly ashamed now to say that I was one of them. Didn't know that this was how it was going to turn out. 

She now often hides and lies about her drinking. She is constantly broke. I feel uncomfortable talking to her about it, mainly because I know it's an incredibly difficult subject and she has been very defensive in the past. But I can't just let her be like this. How do I talk to her?
