There is a difference between being alone and being lonely. Being alone can be wonderful. You get to do what you want to, with no judgement from anyone, and you can enjoy stuff privately. It can be comforting, relaxing, or invigorating...whatever you want it to be. Being lonely is awful. You can be lonely in a room full of people, when those people don't understand you or listen to you. Being lonely means wanting to share your life, but having no one to share it with.
