Im sick of my mum going off at me for stupid stuff?

Everytime my mum gets home from work (8:30 at night) she drives in, gets out of her car, comes inside & says to me ''why didnt you bloody turn the from light on for me how am i suppose to see to put the key in the door'' & she says it like it sounds real snappy & in a bad mood too, & i just put my head down & think how the F am i suppose to think of little stuff like that? im not perfect, i cant think of everything, i turn the kettle on 5mins before she gets in so its boiled for her & ready to make a coffee so why am i getting in trouble for little stuff that is unnecessary. early today she also blamed me for leaving my toothbrush on top of the shower frame, hello???? its a bathroom.. whats wrong with leaving my toothbrush up there? all she does is pick pick pick at things she seems so frustrated, shes 42 i think shes going through bad menopause............................
