As stated, narcisia is streaming currently. Like many of her streams she is largely silent and occasionally sobs. This stream is labeled the end and it seems like they may have said something about going away forever, because the chat is begging them not to hurt themselves. There is little to no trolling in chat, but its very unfocused with people speculating why they are doing this, with no answers from her or the chat.
Finally speaking, this definitely sounds like a suicide stream not a last stream stream.
While vauge, they are essentially just saying they have no optimistic future. That before now there was something they could look forward to being part of, but now they dont see themselves there. They are really careful to always say that they are "leaving", as in leaving streaming. But the context of what they are saying doesnt match with that. For example they said "I feel like a special needs child, who just doesn't belong in this world" and "I feel like my opinion of THIS reality has gotten worse."
