Am I a freaking prophet or something?

I wouldn’t assume they’re going back to a happy/easy life. I can imagine that a lot of them are still going through what they were before, and/or trying to adapt to being back home and in the real world again. If there were other people there because of suicide attempts, they might still be suicidal and worried that keeping contact with people from the ward could trigger them, even if it’s just because it brings up memories of a stressful time. Look at it this way – you felt a lot better while you were there, but they might have felt the same or worse. They might not have shown it, but it’s very possible. So if you saw/spoke to one of them again, you’d think of how you were building a relationship, and it would bring you back to how you felt in the ward when you were making friends. But for them, it could remind them of their illness/issues/past events – which might still be very raw for them. It could even be a bit like you feel now, when you feel rejected and it reminds you of other times you were rejected and felt at your worst. I think the fact that she accepted in the first place showed she liked you, so most likely it’s just her issues.
