want to be at home

I'm a carer for the elderly with various needs I always do a Saturday night... tomorrow at 7am I will leave work for a week and I cannot wait found things really difficult! Does this make me a bad person? My colleagues think it's bad at how much I'm looking forward to a break mind in the fact I'm a full time uni student plus work 35-40 hours a week- I'm shattered and want to see my husband!!
