Hi and welcome ExploreCH!
Would your relocation to Ticino/CH be for the long term or just temporary?
I'm Swiss and local, love NYC and understand exactly what you mean.
Imagine the other way round: a Swiss, living in a small town in Switzerland, everything closed after 6pm, no subway, no theatres etc, only German or French or Italian speaking, loving his/her way of living, telling his/her concern on a NYC-forum about a possible move to NYC. What would you say ?
As a NYC- citizen you learned to discover your city and like the different aspects of it, eventually, you got enthusiastic about it. Wouldn't you tell him/her that he or she may also
like in NYC the exact opposite of what he/she's used to in Switzerland ?
Here's my point: as much as you love the vibrant New-York you know, as much you can learn to appreciate the quiet and calm of ( name of CH-town) here and take advantage of it, and looking back after some years, you wouldn't miss this experience.
If your move would be for the long term, I'd recommand to come over and stay for a while here and see if Switzerland could be
a place to live or preferably not.
