Super Focus Mode: Not always a good thing?

I have been back in choir less than a month and I can tell I am back in super focus mode. Today we sang for a funeral service. I was a little concerned about how I'd do with the service after having a very difficult time with the last funeral I attended. Although I did not sing in the choir for the service back in June.
When I am in super focus mode, I am fully focused on singing the hymns and liturgy. Of course, that is the purpose of the choir singing for funerals in the first place. For the most part, it is a good thing. Whether it's a Sunday worship service or helping lead hymns at a funeral, I am so focused on the music and singing that I often neglect my own personal feelings and needs. It would be nice to have more of a balance, a happy medium.
I don't want to lose my focus as I did in January which led to my very lengthy "time-out" from choir. I would just like to be more cognizant of my needs and feelings and address them as necessary.
