That is true, but a sad conclusion. I don't believe, that there are many people who truly want to be alone all the time. Most just rather be alone, than with mean idiots, who will hurt them again.
But avoiding other people and situations to not be reminded how alone you are, will also never allow you to be in a position, where you can indeed open up and connect to the right people.
This is a really magical feeling. Being connected to people who you like, where you just feel welcome and don't have the feeling to be on your guard all the time. There is a reason many people are obsessed with party and drugs as this will get them this feeling temporarily. But I want that feeling everyday and without drugs. But the daily grind makes it an exception.
