I (17) is frustrated from my family (again)

So basically i am the younger sibling of the house and my elder sister who is 5 years older than me yells at me for no reason like no absolute reason all the time

And it's getting out of hand and my parents are really okay with it saying it's fine she is the older sibling she has stress her college blah blah

But what about me like I get it she is stressed but I am being yelled at all the time and it's honestly affecting me

Like yesterday it was my birthday so it's my ritual to just wake up at 12 am for like 2 minutes and guess what the moment I woke up and as she was studying she yelled at me called me a brat and when I told my mom Abt it ofc she got away with it because apparently she is more spiritual (how does it even matter here ?)

For me my birthday is a big deal and if you can't wish me or cant participate in it plz don't ruin it for me

This made me sleepless like ...did i deserved to be yelled on ? And I was on reddit till 1am because I was so sleepless

And strangers were kinder to me here

Also it's not just Abt this time this has become a constant that is getting out of hand
