It is a mental health issue, it is treatable, and it is preventable.
There is a lot of literature on the topic, and awareness is an important aspect to treating this mental health issue. I never got the sense people are shaming the person, or there is a lack of respect. Additionally, where "thoughts and prayers" will hardly provide any actual good (YMMV), a suicide hotline might be the saving element for someone who may also be suffering.
