My sister and I live completely different lives

We're both short (I'm 5'6 indian, she's 5'1) but her life is nothing like mine. While I'm busy wage slaving in a tech job in complete isolation, no real social or dating life, she's in college with a very active and vibrant social life. Her college experience is going completely differently from mine too. I spent most of my time alone studying, didn't party or have much of a social life. On the other hand, she's in a sorority dating tall white dude after tall white dude, basically living in another reality.

The worst is when she brings her bf and her friends to hang out at the house and they have this condescending smirk on their face... it makes me have this suffocating feeling in my chest and I spend the rest of the night with some very dark thoughts.

Meanwhile my parents are completely oblivious and constantly asking me why I still don't have a girlfriend. Honestly I don't even know if LL can save me at this point, even though it's the only thing keeping me alive.
