MIL help

Currently living with ny SO mom because my S.O got us evicted in november 2016 . it seems no matter all the favors i do and cleaning the house and buying food for everyone is never good enough. I always clean up after myself and my kids and i always get yelled at . tf this is her sons fault i try so hard to do everything . i appreciate everything for letting us stay here . why must i get complained at while no one else cleans or does shit really.. I dont get it so uset rn.
