I can relate. I lived in NYC in my late teens and early 20s, and it was a blast. There was always so much going on, and so much to do.
I did often feel alone, though. The city can be overwhelming at times, especially if you feel lost to start with. I also came from a rural upbringing, and understand the transition. Going to the same places in the city regularly helped me feel a sense of community, even if those places were far apart.
Hang in there, both of you. We're rootin' for ya.
