How can I improve this story with some new words?

When the journey begins on Y shaped path, we feel that the journey will be a great journey ahead but, when we come to the point of bifurcation, we get confused & ask a question to ourself that, where should we go & eventually, we select a path & move on with it. Then further at a point suddenly we realize, we should have chosen the other. But the time is already gone. .. Finally we must accept that we have failed to choose a right way. What if, we had chosen another path, maybe it would have given a great journey.

Can you gimme any suggestions regarding this story so it will be grammatically & punctually correct?
What has written in the story is correct? (few correct) ?

I just have doubt about the sentence “we realize, we should have chosen the other. But the time is already gone”
Here, “time has already gone” instead “time is already gone”.

I know it’s very easy for you to correct me wherever I am wrong .
