Out of commission

My life is a little messed up right now, I've moved into a friends house for the next 10 days to take care of her dogs (a cocker spaniel and a poodle). I stay the night, go home by 8:00 a.m. to pick up Michael, go back for the day, Adi picks up Michael around 5:00 p.m. and then I usually have to work the evening (as a respite care worker), come back and spend the night, and then start the whole day over again! I'm extremely tired. I don't sleep well at their house, I'm a little scared and hear every strange noise. Please pray for strength for me to be able to last the whole 10 days and do a good job!
