Drunk coworker

My coworker/friend got drunk and acted like an asshole. I was on a vacation with another coworker/friend and her other friend. We had a good day or so we all thought.

She drank too much (vacation! So not a big deal) but then she freaked out calling us all names and wanting to drive drunk to a different location because she was refusing to stay in the hotel room. (Me and one friend had a room together, she and her friend were staying at another place. They came to visit and stay the night)

We ended up finally getting her keys from her, although she insisted on sleeping in the car. (We locked her in it for safety) she eventually passed out. Early the next morning she came to the room got her keys and left her friend with us. For the rest of the trip!

It was a total disaster obvi. And ruined all of our trip. We had to rearrange her friends flights to fly the same day as us and not with our other friend as scheduled. Just a mess.

I assumed she would apologize for being such a drunk dick and we could all move on. But she did not and has not spoken to any of us since that happened almost 4 weeks ago.

At this point I’m not sure what to do. We do work together but independently so it’s not like I see her for work. But i could and it will be uncomfortable. I like her and valued our friendship but now I don’t know. I did text her the day after it happened but she never responded to me. She did respond to her friend saying we are all assholes. So she was still mad at us the next day. For what I’m not even sure. I’m afraid maybe she has a problem with alcohol this is not the first time she’s gotten too drunk, just the worst.

Do I let it be, possibly forever. Or do I reach out again and try to deal with it.

Also I’m in my 30’s. She is 50.
