Missed meals, sleepless nights, strange sensations, feeling and seeing what not there, things looking like they are moving when fully knowing they can't, pulling secretly away tired of trying to get better, medication untouched not seeing the point of it and so on... this was both visible but not noticed by others... you just giving up on this...

Now you grab a glass of watter holding your head as it feels like painfuly full of liquid probably from not sleeping? Or is your brain retracting from dehydration... you just want to go to sleep even if it's 9 in morning already but you don't even feel sleepy... When Sephirot see you like this his concerns only heightened he was growing worried sick.
