Maria, I guess chances are that being away from Argentina, you basically idealized the place, the customs, you know the typical melancholy that comes when being homesick, and now that you actually experienced the good and the bad you just didn´t like it. I guess it could happen, why not? Your friend´s parent being killed, etc certainly did not help. Also as a new mother, you tend to get over protective and threats might look bigger in your eyes. I am not saying things here are perfect at all. We all struggle. Not sure how long you have been here since your return, but chances are that you are gonna find yourself missing some things once back in NYC. Good luck! In the end, it is all about doing what feels best and those are personal decisions.
