Is this annoying?

I have a guy friend, and he has been upset and ghosting all of his friends and he told me he feels empty. I wanna be there for him and cheer him up, but im unsure what to do. What I wanted to text him at nighttime saying, "I hope you have had a better day and im here for you if you need it! Sleep well!" And the mornings I can say "Good morning! Have a good day and I hope everything will work out good and the way you want it!!" or something like that but I don't know if that will get annoying or cheer him up and hopefully feel better enough to hang out with us again.
