I think he was hospitalized so he could get keem-o-therapy for the amount of cancer that is Keemstar.
Running away from his problems isn't going to get him anywhere. If he finally realized the problems he had caused, he should've made a video discussing it and coming to an agreement with it. Either way, he's in a bad spot anyways, we'll just have to wait and see what happens to him.
That's true, I take that back. Good job, Keem, you have yourself in a corner where you simply cannot do barely anything to support yourself.
"...step down as full-time host of DramaAlert..." Hinting at the fact that, just as TyBlue was before, Keemstar may come back as a "temporary host" or still continue to make DramaAlert videos but rather have TyBlue to a majority of them and Keem just slipping in when he feels necessary.
