Pretty much what others have said here, but to add on to that, I personally would NOT even broach the topic of suicide, harm, or death, let alone see a mental health professional (unless I needed to for some reason, like gathering evidence for a medical claim or applying for some benefits -- such as SSI or something).
Also, I still find it a bit too risky for me to even discuss about suicide or death because all it takes is some technicality or stupid misunderstanding and then all of a sudden, everything gets worse (including being detained against one's will - even for a short time until they sort it out). Basically, to me it's like playing with fire, except that this "fire" has serious ramifications.
