Happy for you to recovered from that phase, yes i know the ending is bit dark,but i wanted to depict that in some cases people don't even know that what is good for them is actually good or not. Moreover I wanted to show that he just wanted to sleep,to get some rest which i surely missed in game. The thing is he don't feel anything,not sadness,not happiness,just an empty feeling,and he wanted to get rid of that feeling.
