This gotta be a joke right?
Your story is something I would expect form a 4chan greentext.
In case its not: I am happy you can live with this kind of diet but honestly, it just sounds very horrible for me and if I would need to live like that every day I would become very depressed. It's worth to cook at least simple food, just to have some variety in ur daily live and warm meals are so much nicer than eating cold every day.
