Your not alone. It is harder. Growing up when going to school you meet a lot of people and its a lot easier because you see them everyday and have common interests, same classes etc. Also I noticed that as you get older, you get judged more often. Growing up you didn't care about the car the other person was driving/house they live in the wealth that they have. Now a days its like am I worthy to be this persons friend because he/she is on another pay grade. Also smartphones have played a huge factor to this as well, people rather just look down on their phone than making eye contact.
