Get To Know You

So three things to note, one my birthday is at the end of october, two my twin older siblings' birthday is in the beginning of october, 4 weeks after mine, and three this might be long so ill add a tl:dr.
Ok, so last year, for my siblings birthday, my parents got them the iPhone XR, which i was pissed about cuz i didnt even have a phone bc stuff that went down(a whole different story). but i was like whatever cuz my parents usually get food and stuff for birthdays, so this was the first time any of us got an official gift. and then i got kinda excited cuz i thought they might at least get me something nice for my birthday. then comes my birthday and i wake up super excited just cuz its my birthday. My dad woke me up and didn't even give me a happy birthday, which made me kinda sad cuz i thought he might've forgotten. Then i get ready and leave and all that to catch the bus, and at this point, ive had some interaction with all of my family members, except my grandma and older brother, and the only person, out of the 5 other people i interacted with to say anything to me was my older sister. So here I am on the bus, during school, etc and im literally about to cry cuz no one in my family remembered except my sister, and also i had been at this school for like 2 months and i didn't tell anyone my birthday. So then the end of the day rolls around and im talking to one of my friends, and he's like "oh btw, when's your birthday" and im like today and he makes a fuss saying its my birthday and i should've told him etc. And that just made me even sadder cuz he was the second person to say happy birthday, considering there are SEVEN other people i live with from my family. Anyways i get home, go to my room and cry a bit, then fall asleep and wake up 2 hours later. I go downstairs, and everyone from my family is home except my brother cuz he's always late. Then my mom starts texting my brother asking where he is and sees a text from him saying "oh yeah, tell (me) happy birthday cuz i didn't see him and say it this morning. And my mom starts making a ruckus saying that its my birthday, and telling everyone and everyone's like omg happy birthday and i was about to cry cuz they had all genuinely forgotten, and it didnt help that they made it sound like no big deal. Anyways, my mom ended up buying mcdonalds for everyone and she kept on saying something like "omg why didnt you remind me" and i was like 2 seconds away from going off on that bitch. like why would i have to fucking remind you about your own childs birthday, when you can remeber ur other children's just fine? the fuck? what do you mean i didn't remind you? bitch. take ur fat ass roach looking like oompa loompa looking like, fat kid who fell in the chocolate river looking like self out and go to hell while ur at it. Anyways that wasn't a fun day, and im boutta go off on that bitch if she forgets about it this year too. Also today was her birthday, which i actually remembered so yea, im now convinced (for other reasons too) that im their least favorite child. and i should also note my dad doesn't know my birthday at all and calls me over to confirm my birthday for any forms and surveys about me, or that im allergic to peanuts and he offered me peanut butter and was confused when i wouldnt take it and only left when my sister was like "he's allergic". So my parents hate me what about you?

TL:DR my entire family (except my sister) forgot my birthday and im now convinced that im their least favorite T_T
