so i have a big sister that was taking recently pills bc her period was late so it plays too much w her hormones n allat and she cries at least twice a day and so i fr understand her but why do i have to keep consider her all year long while she literally never do the same for me , two minutes ago from this we were sitting opposite to each other and im laying in bed and my back hurts sm bc i js got my period this morning and so she is directing the fan only on her and not letting a single wave of air comes to my face and im already so tired i asked her can u please direct it for me for a little bit and use the other little fan ? she said im too lazy to get the other fan and then like mumbled smth and i js wanted to scream at her cuz she always do this and always never think of me literally she acts like a robot she never remembers my birthday she never remembers my favourite colour or anything even tho she asks us to remember her, should i talk to her or consider her hormonal changes?
