feeling a little low

i am so tired..and it is because of things at work and at home..at home my mil has gone away for a short holiday..that means i have to take over the role of a mother in the house....daddy has been really great..he will automatically help me with the chores but overall it seems like i am still left in charge of everything..it just frustrates me till no end that the sack of rice just gets away scot free...he does not even do anything different to try to make an effort....i still have to go and pick after him....he is really a true pain in the ass...as for work, i received a bad piece of news..one of my new colleague has just resigned...leaving end of the month for a better job offer and she just joined us like 2 weeks ago....i am worried coz that means the school does not have enough teachers during the weekends..i am just worried that i will be the next target to try to switch me to work weekends...daddy assured me not coz i have already previously addressed my great displeasure in working during the weekends..daddy said they probably will not want to rock to the boat coz i am considered the only english teacher who is experienced....i hope so...i just feel so exhausted...help me
