I'm losing strength.

As day by day passes, I feel that I am becoming weaker.
I have to face so many things at once and I just couldn't take it...
First, I had lost a trusted friend.
second, I receive an unsatisfied results.
and thirdly, I made lots of mistake for my Biology Topic Test.
What is happening to me? I feel that something is taking control of me...
I'm losing my strength, and hopes.
Maybe ending my life will be a better choice...
