it's bad that to just be waiting for someone else

I feel boring bored and sad when I have been waiting for someone for a whole day long. The worst thing is that I was told that I have to wait for longer just as the appointment time arrived. I am sad because it seems that I don't have control of my own life. I'v thought it's   was good thing of looking for something worthy. However, now I just feel bad, I always believe the promises that never come true. I wonder want to find a new life, where i can just be myself.
