A world Problem: Suicides

Since this year, I av been reading posts about teenagers committing suicide. 

Just this morning, it’s was about an 18yrs old boy committing suicide because his pregnant girlfriend also committed suicide.
Now my question is why suicide??? Is it suppose 2 b d last resort to tough situations?? What causes it? Which group of people does it affect more? Youths or adult? Then what’s is schools, government, churches or whatever doing to tackle this problem?
