Time for a break?

I think I need another break...
The Doctor seems to think its due to stress that my immunity isn't working so well thus making me susceptible to germs/bacterias and viruses. I was so sick last week and just when I thought I was well, my sore throat returned with a vengeance along with a nasty cough.
Since the year started, I feel that I am running on a treadmill programmed to move faster faster and faster and should I should slow down I think I will crash and burn.
The biggest irony being--IF i really take a break now I will end up being more stressed!!
