aww, sorry to hear that :( take it easy i hope you soon feel better :) yes any comment with good intention is better than none even one simple word (or two?) and in times i don't know how to put into words what's on my mind i comment something :) ( i didn't count how many times i made comments on visual novels and rpg maker games, i think all of them unless i forgot by mistakes hehe)
a few times i'm the only one who makes comments on them too..it's a bit sad if you ask me.
take care of yourself :)
