How do you deal with bitterness and jealousy when you see less deserving people living your dreams?

So One of my classmates last year got in to IIMC at 91%. Since then he has been posting non stop about everything thing that happens on whatsapp, linkedin and instagram. He posts about every small thing that happens in status like " Sunset from IIMC", " enjoying a beer after a long day at IIMC" . When he finishes an assignment there would be status updates like "Assignment for XYZ subject done and dusted @ IIMC".

All his posts revolve about some events from the college. I mean I get it you made it into a tier 1 college but what's the point of regularly flexing about it.

Recently he got into a relationship with some college girl that he is supposedly guiding and helping her prepare for cat. So all the couple posts combined with the institute flex is really turning me into a very bitter and spiteful person.

it’s like he’s trying to make everyone else feel lesser by constantly putting his best life on display. And as much as I try not to care, it gets hard to ignore when i have no tier 1 calls at 99.56%. It is making me feel worthless in life.
