This was really amazing. I actually related a lot to this story. Although I don't have narcolepsy (my mom does, though), I do have clinical depression.
I'm not quite sure when it started, but as time went on, I just started losing interest in doing the things that I used to love. I even started holing myself up inside because it felt like the energy was just physically drained from me.
I actually also love writing, and I hope to become an author, even though I only write fanfiction online. Even now, despite how much I love pouring my heart out in words, I have times where I'll go weeks or even months at a time without writing anything, because I just can't muster up the energy or the motivation to do it. It always makes me feel like I'm letting people down.
In the end, I still haven't found any medications that help 100%, because there isn't really any magical cure for depression, and I still have days where I just don't have the strength to get out of bed and I just feel empty inside. But I still know that I do have family and some friends that do care about me, and it does help me through the days.
I hope this game will help other people out there who also suffer from some sort of invisible illness, and let them know that they aren't struggling alone.
