@MARYTHEBESTe hi! I'm not sure what you were referring to or feeling guilty about, but I just wanted to tell you that Lyric's alive. I was friends with them irl before my family moved, and we're still in contact via text. Their mom banned them from Wattpad, which is why they left. (I don't really have evidence for knowing Lyric irl + them being ok except that they used to comment on my message board sometimes back when they used Wattpad, and they replied to a comment above yours in march 2021, so it's ok if you don't believe me.)
I just wanted to tell you that although I can't speak for how Lyric feels, they're alive + physically safe, and their mom and close family support them being non-binary. And I'm sure they're glad to have been friends with you, you sound like you care about them a lot. Idk if anything bad happened between you, but it seems like you're being a bit hard on yourself if you just didn't notice exactly how they felt - no one's a mind reader.
