I tend to agree with the above.
When one falls into suicidal depression, general "inspirational"
talk is honestly the last thing he/she needs. Trying to push
your own perspective of life onto the person is
akin to trivializing their problems.. almost taunting them. It
would re-affirm their thoughts that no one understands, no one can
help. What they need is a listening ear.. someone to just be there,
a silent pillar of support. Not uninformed or righteous
advice.
Remember, you'r'e addressing a person with a skewed outlook on
life, pushed to the edge.. someone with a temporary mental
imbalance. You dont know
their problems. However well-intentioned your words or actions may
be, it can and will backfire if you simply proceed the way you
think is right.
