I tend to read up on potential cures that may come in the future. Even ones that are far off or unlikely. Hope is a valuable coping mechanism.

I busy myself with tracking the parameters in my life that make me feel good or bad. I take care to track the things that make me feel good and I don't have a "Pain Journal" but rather a "Thriving Journal". The semantic distinction changes my attitude toward the process.

I consistently pursue every currently available medical treatment. This is part of keeping a positive mindset.

I try to fully and mindfully appreciate the good days. I hope you have good days, or at least better days, to focus on. On the worst days, I try to reflect on the fact that a better day will come around eventually. Maybe tomorrow, even!

I assiduously avoid letting myself dwell or ruminate on "how much my life sucks" in such terms. I focus more on how I'm doing pretty well, considering. I've learned that getting into a depression about it just makes everything a billion times worse. Call it stoicism or whatever, it's more like a mindset that depressive thinking is an addictive drug that I know I can't risk taking a single hit of or I'll be addicted.

Suicide is not really an option that bears much thought when you consider that literally tomorrow somebody could come out with the cure to whatever ails you. You never know. And once you're finally cured, physical pain that's in the past is not really real anymore.
