What would mean this needs more than a course

These sit in lesson one and not at the end, because somebody in a bad enough state may never get to lesson six.

You have thought about ending your life, or you have thought that nobody would notice if you were gone. That one goes first and it goes today.

You have not spoken to another person in days, and it is now weeks rather than one bad week. You are avoiding contact because of fear rather than preference, and the avoiding is spreading. You cannot leave the house. Your isolation started after something happened to you that you have not been able to talk about. You are drinking or using something to make contact possible, or to get through being alone.

And one that is not a mental health marker at all. Someone controls who you are allowed to see or speak to. That needs a different kind of help, and it exists.
