WHAT DO I DO WTF

yall okay so my grandma is making me write an essay for my older sister [3 years older] because im really good at reading/writing (i was a 7th grade level in 2nd grade and now i "read alot" but its mostly fanfiction, still love reading and writing though).

she was supposed to have roughly 2 weeks to work on it, but they gave it to me YESTERDAY. AND THERES LITERALLY 3 FUCKING DAYS LEFT TO DO IT.

yesterday she pressured me about it and i have to read a 300 page book on it online before writing the essay but she wanted atleast some done so i told her the introduction and the 1st paragraph... SHE TOLD ME SHE WANTS IT DONE TODAY. BITCH WHAT???????

AND SHE ALSO WANTS ME TO WRITE IT FROM A DOCTORS PERSPECTIVE BUT THIS IS ABOUT RACISM IN DOCTOR SHIT, BUT IM IN SOUTH USA AND SHE CALLED BLACK PEOPLE "BLACKS" IN REFERENCE TO POC "BEING SELFISH" FOR THIS SHIT... BUT IM NOT ON THAT SIDE I WANT TO WRITE IT FROM THE FAMILIES PERSPECTIVE.

and she wants me to write it from the doctors POV but this is about that HeLa thing??? AND i think that the doctors were at fault in a way???? AND SHE CALLED BLACK PEOPLE "BLACKS" IN REFERENCE TO POC BEING "SELFISH" FOR WANTING MONEY FOR THE CELLS OR SOMETHING- AND IM SO,,, EEK. Im Not even on the fucking doctor side of shit i WANNA WRITE IT FROM THE FAMILY PERSPECTIVE, but i think shed YELL AT ME BRUHH.

not to mention i cant do SHIT under pressure and im on the first FUCKING sentence right now. IM ON PAGE LIKE 20 OF THE BOOK. GOD HATES ME BUT I CANT LET MY SISTER GET A BAD GRADE ID FEEL LIKE SHIT.

also I got diagnosed with autism like yesterday so im super fucking STRESSED LATELY ABOUT IT- but after the diagnosis shes just been putting more stress and shit on me about it because the doctor told her to challenge me [THE DOCTOR MEANT IN SOCIAL SITUATIONS] and she took "writing is one of fuyuhikos special interests" meaning I CAN WRITE ESSAYS FOR HER???

SO LIKE WHAT THE FUCK AM I SUPPOSED TO DO???? ANY ADVICE?? PLEASE HELP ME
