They need to get the balance right - he needs to focus on his health, but also it's not going to help him (given the responsibility he feels towards the show) if it suffers because of this. So they need to get the balance right, for his sake as much as for anyone else's.

I could cry because of this - they messed up so much this season, and all the fuss and bother because of it can't have helped him. Plus his workload seems to have been insane - the other main characters got less screen time, but he seems to have been working just as hard if not harder than last season. I'm just glad he's finally been able to admit that he needs help and ask for it - that's a really tough step to take.
