Dear Sir or Madam,
As a near native English speaker and accomplished writer in my field, I believe I can be helpful to you by doing some research and reflection on the topic you need. If you let me forward you an idea, I think that one of the reasons suicide is higher nowadays than before might be due to a kind of anxious feeling of nowhere-to-escape one gets when confronted to a world with so many wars, environmental issues, poverty and violence. This is purely intuitive and it comes out of my own experience, abstracted to many. I would be glad to know whether you want a subjective point of view or an objective one. Please contact me for further discussion, if you like.
Thank you in advance,
Luis
