we are in our early 20s as well just moved to South Norwalk from Florida, my partner commutes to his job in Wilton in about 15 minutes if you take 7. People in CT have been much friendlier than where we moved from and as for seasonal depression we just try to get outside every weekend on hikes and have a cup of coffee before the sun sets at around 4-5 but it was not bad at all to get used to
