Depends on the circumstances, time frame, and probabilities of different amounts of suffering. I would probably optimize for maximum expected personal comfort subject to financial and physical constraints, and I would probably come up with a "ripcord" (fast suicide plan with all required resources and practice deploying it) in case things get too intense. Personally, I'm more afraid of the "going" than being "gone".

Or should I humble myself and go through suffering before I die?

Not unless you want to, for some reason. Choosing the manner of your demise is the ultimate act of bodily autonomy. It shouldn't depend on your culture's preconceived notions of death.
