Someone who matters to me is greatly suffering.
This is meant for them and anyone else who may have the question:

Among other sources, reading the following philosophical and theological discourse (starting past the introduction) has helped me.
(I recommend reading rather than listening since in the spoken talk she skips or gives less emphasis to some of the most important ideas toward the end.)
