I'm a strange blend of existentialism and Catholicism where I started with "life is objectively meaningless so we make our own subjective happiness" and suffering was a thing that just was and you dealt with it just like anything else. Suffering is also subjective per person so what may be unbearable for one may be daily baseline for another.

Catholicism has a concept called "redemptive suffering" where your suffering is offered up as a spiritual sacrifice, often for a loved one who has passed away. We usually can't choose not to suffer but we can choose how we respond to it.

Modern Catholicism also has no issues with evolution so generally the "life is infested with parasites and therefore can't be declared good like the Bible says" is a fundamentalist problem to try to explain. Evolution appears to be how life got to its present stage on Earth and we have the history encoded in our DNA. Arguing against that is embracing blind, stubborn faith and ignorance.
