I think the inference here is how to deal with the issue of losing someone rather than "overcoming" death itself – the loss of a loved one

Perhaps a less literal word is needed here, due to the subjet matter and your comment in azmi's suggestion.
תפישת litearlly means "to grasp", and in this context, to grasp the idea of death, its meaning and possible influences on our daily lives.
התמודדות or התגברות suggest a more specific idea - how to deal with or how to get over death, and if I understand your context, you need something that is more general and relating to our ideas about death - in life.
Hope this helps
