I get this sentiment, but the best way to combat this feeling is to build community.
Get to know the people around you. It starts small by just ditching the headphones in public and saying hello (and maybe some small talk) every time you encounter someone. Then start offering and accepting help, plan events, and keep track of their life milestones. People will be so pleasantly surprised when you remember things about their lives.
And you will probably be surprised at how many interesting people you pass by every day while keeping your head down. Over time, some of them will begin to reciprocate. Remember, they are probably also starved for community.
Capitalism wants us isolated, sad, and reliant on their products/services. The antidote is strong community.
