Who is the loneliest among the twelve constellations?

I think Pisces likes fantasy, the feeling of love, sincerity to friends, attention from others, but most afraid of loneliness. Pisces is born romantic and pursues the standard of perfect love, so it wants to get perfect love. Pisces are naturally fond of fantasy, so they only have imaginary friends in their minds. They are eager to have someone who can fully understand themselves. But in reality, no one can fully understand himself, so he feels lonely and is afraid of loneliness.
