When one feels home sick, i.e. misses one's home and lifestyle, in his/her own home due to the prolonged stay of uninvited guests. There is literally guests' stuff everywhere. Whatever they like is being cooked too. They practically never wanna leave.
You are in your own house, but not really. Life begins to suck.
"My aunt has been here for two weeks now."
"Really? That sucks. How are you coping with it."
"I am going for counselling, cuz I feel home sick at home."
