Gaslighting pathatic Biological Mother (dont even want to call her mother)

 I was sitting in my room and door bell rang. i waited because two people were already at the ground floor so I thought I don't need to check , after few seconds the bell rang again and i got up went to the balcony to check if they have been attended. the servant was brooming on the same balcony but he ignored was he deaf idiot !! I went to the ground floor to see why no-one is opening the damn door so i saw my elder sis sitting in dining room inside her mobile phone and my mother in the kitchen cooking. neither did the elder sister hear or got to see nor my mother checked or asked her to see who is there. i was irritated but i helplessly went to the front door and opened up surprisingly my father was also at the back door but he also ignored WHY?? I mean what is the problem with them. I came up. after few hours the door bell rang again and I hoped that this time they will check but then the bell rang again after 5 minutes as usual I went to the balcony and saw that the water delivery guy was standing and no-one came to attend. I went again downstairs and checked the elder sister was sitting in front room just beside the main door which was wide open, two more people were sitting there as usual the mother was in the kitchen , she again didn't ask her deaf daughter to go and check neither the mobile head daughter got herself up and tried to see who is out there. I went and attended, then i asked my mother why is no-one checking the door i came down twice and no-one in the ground floor is checking this, then she started hauling on me taking out her frustration over me because she had no guts to shout on her elder daughter but she had choice to spit on me who was actually doing the work. she has such filthy favouritism they she will use me as her dustbin but wont say a word to other children, I have realised and accepted that I have no mother and I don't want such a shameless and such a hypocrite in my life. I want her out of my life FOREVER. because this is not for the the first time. is rishte ki chita jal hi jaye to behtar hoga !!
