This is misleading. All problems are easier to bear when you are connected to people dealing with the same problem. Conversely, all problems are harder to bear when you must deal with it alone, particularly when you feel you MUST deal with it alone. The implication is that if you feel lonely you should not seek out others, but rather others who feel lonely. They will understand you, and you them, and you can talk or sit or simply know that you exist, in far larger numbers than you'd expect, and find great comfort in the thought.
