Bad mood

My college entrance examination is over.  I have prepared for this examination for 3 years, but what have I gained in the end? I haven't finished my test paper and  I have left many examination questions left. That is really sad for me.  When you have tried all you can do, but earn very little, you will feel disappointed, sad, angry and even hopeles.  All of the bad emotions are coming come to me.  I don't know what I should do next, I have lost my direction.  I am now afraid of what's going to happen  to me in the future.  (I hope you can give me some advice after reading this passage, I need your help.)  Don't forget to corret my passage.  Thank you.
