FIL is 72. He had a terrible childhood and had a career which involved life-threatening situations on a regular basis, so at the very least I would imagine he has some form of PTSD.
About a year ago he developed a back problem, which has caused him pain and insomnia. This, alongside his usual fretful state has driven him to talk of suicide.
MIL is reliant on FIL for most things as she is in poor health herself (mobility issues, brain surgery, cancer). She and DH have attempted to persuade FIL to at least get counselling instead of looking for a magic bullet to cure his pain/insomnia. He is old school and won't countenance it.
DH at his wits' end and has asked me to consult the MN hive-mind. What can we do to help FIL? What help is available to someone who won't discuss mental health issues? Who should he see about his back (he's had injections which didn't work)? How does one convince an intransigent person to seek help?
Thank you
