Confused Soul Seeking -- The Best Friend..!!!

In this life, many relationships develops everyday, every hour, every minute and every second.
Out of all such relationships thus formed, the relationship of frienship is something which is most common and perhaps this is one thing that everyone cherishes because:-
Friends cry together..
Friends laugh together..
Friends share together..
Friends eat together..
Friends grow together..
Friends love each other..

.........and they indulge in things that can't be expressed through words.

But do they stay together for life is one thing that confuses me... because as friends are common so is the common law of nature -- " Life moves on."

So who or what stays with us? Yes... friends rather best friends stay even when they are not near. They always provide a support system whether in their presence or absence.

This gives me a fear - A fear of loosing, loosing the best friend. Most often it has happened to me that I have lost despite of my measured steps.
Once I consider someone close, someone for whom I care -- I start living in a constant fear of loosing. I hope that God is kind enough not to make me confront such types of situations again and again because it hurts and this hurt is very painful.

Thats why since childhood I considered "My shadow" to be my best friend, but even the shadows leave, when sun doesn't shine or when the weather is gloomy and when I relate this with my best human friends, again a fear of loosing starts creeping in.

Just today I read that Confucious once said, "Silence is the true friend that never betrays." This statement took me to a state of bliss or rather in a state of silence where I met a new friend.

Now I am confused about who my best friend is? Is it a human form? Is it my shadow or is it the Silence??
