"Help is out there" can be a well-intentioned message to someone struggling with mental illness, but it's also very often a thoughtlessly shallow, meaningless cliche.

Help is out there... if you're lucky enough to have the resources to access it.
Help is out there... if you fit into one of the pre-existing patterns that the system expects and is prepared for.
Help is out there... as long as you don't need too much of it.
Help is out there... in an abstract philosophical sense that may have no relevance and benefit to you.

If someone needs help, if you can, get them access to a specific resource that has a good chance of being helpful to them.
If you don't have the time or energy to do that, please don't substitute that with empty cliches, even if they happen to be popular ones - because you maybe simply amplifying falsehoods about the existing system, and dismissing the lived experience of many people that are mentally ill or suicidal.
