Why am i starting to dislike my parents?

They getting so infuriating. I am a good kid i've never disliked my parents. I always do as they say and i respect them a lot. But im not sure whether im just tired or im starting to not like them. THey're pestering me about getting a job, helping around the house more and studying. Im doing a very competitive degree which i am now on holiday from. I was very stressed as it came to the end of the semester so i thought a break would be lovely. I havent looked for a job and i totally understand them wanting me to get one. I know i should start studying also. I am constantly asking whether my mum needs help around the house and she always rejects my help. She was grumpy about my room being messy when i had tidied rather than cleaned my room and bathroom. I think its the way she keeps getting grumpy at me i cant handle it. I am very grumpy. WHat should i do to fix things? I feel like im constantly being attacked and whenever i express how i feel it just gets turned around either that im too sensitive or its my fault.
