Advice for a friend ☹️

Anyone have a friend who is feeling “lost”? I am currently 28 weeks pregnant, married, and have a nice house. She’s a few years older than me, no bf, lives with her mom, and shuffles between “friend groups” because she always somehow ends up pissing everyone off. Anyway, she just recently posted some pretty sad stuff on social media. I tried talking to her, but all I got was “I don’t fit into your life anymore, you have everything and I’m a fuck up”. I feel horrible, and she’s not answering any of my texts.

Any advice I could give her? Other than what I’ve been saying, which is I’m always here for you. I don’t want to be rudely blunt and say “stop partying, stop going after fuck boys” but everyone tells her that and she doesn’t listen. I’m afraid she’s going to go over the edge.
