Feeling useless?

So I'm from an Asian family. My older sister was born in the year of the boar/pig (1995). I was born 2001, year of the snake. And in Chinese culture, it's difficult for boars and snakes to get along. And well, my older sister has a habit of calling me "useless" around the house. Because I don't help out as often. Well, I say bull, because I do help out. Sure, I'm always in my bedroom, on my laptop, daydreaming and watching YouTube, but I do my fair share around the house for my parents. Take out the trash and recycling. Fill up the water pitcher for tea, take the dogs out (to do their business), etc. And yet I'm still called useless by my older sister.

Okay so, maybe I am I'm always in my bedroom, on my laptop, daydreaming and watching YouTube, but at least I'm doing minute/small things around the house, but at least I'm doing something right? Doesn't that count for anything? And every time I get called useless, I get mad and sad. Sometimes, even feelings of suicide. It really does hurt my feelings. But it doesn't matter, my sister gets scolded for calling me that. And as time passes on, it'll go back to "You're useless. You don't do anything around the house besides stay in your bedroom." And the cycle of hurt feelings repeat.
