Need a rant

I live with my partner and his mother (she has a partner and he stays twice a week), both myself and my partner have been struck down with flu and also developed a chest and sinus infection as a result this week. Despite knowing how unwell we've been she was harassing my partner on his worst day to give her £200, despite having already paid £450 in rent. Her and her partner have just gone away for four days to a caravan they own and they've left the house like this, I'm so disgusted that anybody would think its okay to leave your house like this!!
