People tend to stay within their social circle, within their fishbowl. They are always in a place near their friends and loved ones. Some people choose to go out of their "fishbowls" and live in other places. There, they become alone in front of strangers. People look for friends as fishes look for other fishes.
Once they fit in their new environment, they are now in a new bowl with other fishes. They may be happy and contented but there will come a time where you think of the past. The time when it feels like you are longing for the "water" that you are used to. It's the time when you think of your dear old friends. There comes a time when you are happy in the present and it brings back the past. The memories of your loved ones, those happy moments.
"Only in quiet waters do thing mirror themselves undistorted. Only in a quiet mind is adequate perception of the world."
Your friends are far away from you. They are in another "fishbowl". Go back to where you came from, even just for a little while. If you are lost, don't give up. Go back to your friends. You'll see that the other fishes are waiting for you.. Hoping to see you again.
Friends are friends. You should "water" the seed of friendship that you implanted on each other. You should reach out and communicate with them. When you feel alone, find a friend and you are not alone anymore.
“I hold this to be the highest task for a bond between two people: that each protects the solitude of the other”
-Rainer Maria Rilke
