Making friends in late 20s is impossible

I am 28 years old making ~28LPA as a Product Manager. I really enjoy my comfortable life and it is always good being financially independent.

I sometimes wonder if I had an emergency would anyone even show up. At college, I had a great circle of friends, but there hasn't been one person I connected with deeply since I stopped studying.

My colleagues around me constantly invite me to drinks, some superficial conversations about weekend plans, even though I am actually looking for real connection and more.

The forced team outings and fake enthusiasm makes me sad beyond belief. It is almost like I give so much of energy to socializing and although everyone is polite but no one actually cares about me.

People my age constantly try to retreat to their old school groups or just sit in their apartments.

Spending this whole Tuesday evening entirely alone makes me want to give up on trying. I think the mix of remote work(isolation and screen time), constant exhaustion and the time I spend away from my college friends makes me lonely as fuck.

I am now understanding that you can never build real friendships in adulthood because you can never recreate that college environment. You think moving for a job will make your life exciting but you will just end up losing your social skills.
