I’m not sure if this is the right subreddit but I wanted to post this here incase anyone has advice. I’m sat on a train and there’s a girl near me having a full blown conversation with herself. I once lived with a girl with psychosis and schizophrenia and I always want to do what I can to help people who might be struggling. 

Should I say something? Is there advice you would want to hear if you were in public? She is v clearly anxious (twitching and shaking) so I want to do what I can. 

Any alternative subreddit suggestions welcome. 

TIA 🙏🏼
