Being alone doesn't kill; it's the feeling of being lonely that does.

It hurts when you feel your heart is lonely, but know you have nothing to do but just listen to your mind and wait.

Nothing is more boring than feeling lonely. You could be bored of people but not feeling lonely, and you could be surrounded by people but feeling lonely.

Do you know what is the most frustrating thing in this world? It is not having someone to return to when you are tired, sad or lonely. Someone you could really trust, someone you could really talk to about anything and feel completely safe and understood, someone who really cares about you, fears for you and can’t rest without seeing you happy.

The pain of having lost something is never equal to the pain of having lost someone.

It always hurts to realize the other person has got over you and moved on with their life while you are still where they left you, crying over them, and waiting for them to come back.
