Sorry to hear about your sufferings, sideways. If you are having strong suicide ideations, please do contact the crisis line in your local area and seek counselling. Talk to your love ones. They are the one who can give you the support you need.
Have you had the kind of prescription to control the pain & headache? I have a friend who had a bad cancer operation on the sinus and had suffered bad nerve pain and he has to take a chunk of pain killers every so many hours. Perhaps you can join a chronic pain forum to get support for the chronic pain.
When I had my ultra high pitch loud T and severe hyperacusis, I have learned from the late Darlene Cohen who suffered from acute chronic pain and had to be bed ridden at her young 20s for sometime. She somehow found her way to cope with her pain with an approach which she called it 'Finding Joy Amid the Pain'. She recently passed away with cancer in her 60s. So she did survive that long with chronic pain and she was teaching people how to cope with acute pain. I am no expert to counsel people with chronic pain. Perhaps you can read up her writings.

I have grandchildren too and I have ultra high pitch dog whistle T which could be heard above the jet noise in the last two fights I took. Finding joy amid the pain, that is what I learn from Darlene Cohen and it has helped me. Hang it there. Life is precious. You offsprings wil need your wisdom and support as they grow up.
During my worst struggle with T, H, anxiety and panic attacks when I suffered daily and hourly, my last resort was meds like benzos, anti-depressants, sleeping pills, as well telling myself just donate my body for my love ones. I am not comparing your sufferings to mine. Each person has unique struggles. But at some point, when the mind keeps on floating the 'S' word daily, and the body and mind suffer so much, I just treated myself as a 'composted' body, like in nature mother plants compost themselves so the seedling plants can get the nourishment to grow up healthy & strong. I accepted my sufferings as if I were a composted piece of junk but dead and insentive to hurtful sensations. No more struggle with them. At least I could massage my tired wife daily and hugged the chilldren/grandchildren. I never thought I could make it through back then a few years ago, but never say never, I am back to living a normal and enjoyable life. Time has done some healing. Don't give up.
