Man that story is so heartbreaking. I'm glad u recovered from this. I had a similar story but it wasn't that tough as your story.
Once I got a covid, and I felt so bad. I was lying on my bed 99% of time. I couldn't motivate myself to get up since I felt so wasted. There was one game that helped me survive this stupid covid. NieR Automata. When I was so worried that I might die and not survive, NieR took all my worries away. I forgot that I'm sick and even tho I could only get up for like 2-3 hours to play, that helped me a lot. Fixed my mentality and all worries. It wasn't only my favorite game, it was also my saviour.
