Most Helpful Guy
You've always been lonely, and you will always feel this way eventually until you address the core reason for it. When you figure out what is causing loneliness, it becomes solitude... it becomes beautiful and freeing.
Then instead of needing a relationship to fill a void, you only have one because you want to.
Often I think loneliness is due to lack of knowing yourself at the deepest levels. What are you beyond that which society has labelled you? who are you? what is the purpose you were born to do?
If you are thinking about what I've just written... but you know you are thinking, who or what is it that knows you are thinking?
Know thyself, and never feel lonely again.
The mistake most people make is that when they feel lonely, they get into a relationship instead of transmuting loneliness into solitude. Then when the relationship ends, they discover they are still lonely.
