I confronted my friend F 21 about her drinking and now in a group she’s making fun of me F 21 more than usual

So I’m part of this dnd group and there was this girl who didn’t come very often. She started joining more frequently and everybody was happy because they were worried about her. The time we did hang out she got sloppy drunk puked everywhere and even though I didn’t know her that well everyone thought it would be best for her to sleep over at my house because if was the closest around. Everyone said it was a habit of hers to get really wasted and drunk often. We all had to sleep on my house with some people in the living room on the ground to watch over her. It was pretty awful. She was talk in our chat about getting drunk a lot. As we got closer she’d text me saying she was drinking alone, drunk alone, tipsy etc alone at night. This concerned me greatly. I talked to everyone about this, the guys didn’t care at all and the only one concerned was the other girl in the group who was too scared to confront her because they weren’t close enough or something. I tried to reduce alcohol during our hangouts if she was there. The other week I just got fed up with it and very worried because she was texting about getting tipsy/drunk again like always so I sent her a message telling her I was worried, that I care about her that and that I think she should reduce drinking alone because it was unsafe at night as a woman that whatever problem she was facing we could solve it together that she didn’t need alcohol to try and feel ok. I know I made a mistake because immediately she shut me down and I realised I should’ve done it in person but we’re never alone and always in a group. I had invited her out before and it’d just never happened. She stopped responding after I apologised and told her I wasn’t trying to control her or be judgmental I was worried and hoped she could come to me with any problems or worries.

We met for dnd and she started making digs at me. My friends and I tease each other but she really was acting different. Maybe she was just trying to join in with the guys but I sensed something was different I don’t know how to explain it. And my sense of things tells me she’s upset because of the texts or that I brought the drinking thing up at all. My other female friend didn’t show up but we messaged and she said that the alcohol friend doesn’t like to be confronted with her issues. I did also try to talk to my guy friends about it but the dm of our group but he just said as long as I don’t care scare her away he doesn’t care. That I should’ve just sent fewer words that my text was too long. But I just feel like everyone else is a coward for not talking to her, for enabling her for so long. How can you just sit back and watch your friend self destruct without saying anything? I feel really bad.
She’s kind of being an asshole to me more than usual. I know I didn’t text her in a proper way or I should’ve called, I know I didn’t do it right but it was genuinely just out of care and I made sure she knew in the messages I just wanted to be there for her. But now she’s being kind of passive aggressive and making fun of me frequently.

Tl;dr
I messaged my friend about how her drinking was unsafe and starting to get out of hand and she pushed me away and now is acting different around me and being meaner than usual
