Why do they commit suicide? Is it because they want to die? Or there's a reason

"There's always a reason in everything. No one commits suicide because, they want to die, they commit suicide because, they want the suffering to stop, they don't want pain anymore..they do it...for selfish reasons"

But....but, why would they waste their precious life? Life is beautiful! And death is Painful!

"Well...Life may be beautiful but, it's full of Lies and Death may be Painful but, the truth is within it

Life is a beautiful Lie and
Death is the Painful truth
