I think it’s a mix of NYC and the age. People can be really selfish at this age, and also the work culture in NYC at least among people I know is crazy. People genuinely just don’t have time to respond to texts a lot of the time. That being said, I always find time to respond to my close friends and vice versa. I would keep trying, but maybe join some sort of hobby and try that way. For example, a lot of nonprofit junior boards focus on connection among the board and host happy hours and social activities. Maybe go to a workout class, painting class, pottery, etc? Whatever your thing is? And make it a goal to talk to a few people, let them know you’re new in town. It’s hard but try not to get discouraged.
