For starters...
It's definately just not teenage girls, I know a lot of guys who have wanted to commit suicide. Even I myself have wanted and once even attempted to commit suicide.
Like a few people have said, I believe modern life is so fast paced with fashion, idols, schooling, bullying, peer pressure, and many other factors drive people to such drastic actions...
I know numerous people and pretty much all of my friends have attempted or have thought seriously about killing themselves.
One of the only ways I believe can help some people (but not all) is things like counselling. When I went to the GP with depression, they said the best thing for me was counselling, so I agreed.
At the time I lied about attempting to commit suicide, my parents had refused to leave the room and I didn't want to admit to them.
This was all during the summer of 2006...
I AM STILL WAITING FOR MY COUNSELLING SESSIONS!!!!
The government are to blame for this I believe, they should have more depression-wise counsellors on the NHS.
Afterall, they're constantly going on about people who are dying from cancers due to drinking and smoking and obestity, people who are killing themselves deliberately, seeming stupid.
When younger people, who are the future of this country are commiting suicide with no chance of help or even care.
The government should employ counsellors to be in schools, colleges, etc and talk to students as a group and individually.
If you can't take away a problem, at least try and help it a little.
