And then something better comes along and you don't have a clue on what to do because you are afraid, confused. You want it but it seems unfair. You feel like it might be the best thing for you but then you do nothing about it because you are tangled in this knots of confusion.
And then this "could be the best thing happened to you" goes away and you actually missed you chance. Of course we know that if it was meant to be it will be but you had let go of the fear that was holding your back. Now, you are back to square one. still afraid, still confused and still lost. Only this time, it is twice the hurt and twice the pain than it was before.
