My protagonist is a 19-year-old female werewolf who was separated from her parents and her pack at the age of four and was taken in by a magician. Since she was 14, she has been investigating and searching for her old pack. Now the story is not about her finding her pack, this is simply her initial goal and what drives her at the beginning of the story. Later on, she finds out that an organization wiped her pack out years ago. The problem is, how do I effectively portray the impact and grief this will have on the protagonist without making it over the top angsty or making her unrealistically strong throughout the ordeal. One of the key elements of her character is that she rarely gives up and is a "keep moving forward" kind of girl. But I know this is something that will make her falter. How do I effectively portray something like this?
