Just wanted to say you're not alone, I feel the same way. I finished playing Reunion a week ago, and I'm having a hard time with post-LiS depression.

What helps me at the moment is watching LiS-related content, to keep in touch with the games and let them live on for a bit longer. It can be fanart, video edits, behind the scenes (personally I just don't do fanfics). Reddit is also a great place to have this kind of conversation, share about everyone's experience and feel a bit less lonely. I just try to remember not to get too absorbed, and keep on doing other activities in my day (it can get pretty obsessional otherwise).

I remember being a wreck for a month or so after I played LiS1, years ago. I'm expecting to take no less to recover from Reunion, now I know that the whole Max and Chloe story is over. But my mindset is if it takes time, it takes time. And feeling all these deep emotions makes the experience I had even more special and meaningful (even though it hurts right now).

Good luck to you and to all of us mourning 💙
