I can't just reply to questions and be done with it (so you can skip my reply if you wish).
I work in psychiatric ward and get sometimes called to help when there are patients who are suicidal and have CH.
Very, very often when CH is managed to get under control, the suicide plans vanish and again, very, very often never return.
But there are people who have more complex problems and conditions and need help beyond getting CH under control. Then you need to keep reaching for help - relentlessly as long as you need, or better yet - find a support person who helps you fight.
And it's incredibly tough when the things that work for others do not work for you - these people would need a community of their own. People with torturous chronic pain - whatever the diagnosis or no diagnosis at all, who have not yet found help and those who have found something that helps mixed in one group.
I hope you keep reaching out and find help.
