While it's true that Nelly Dean was a constant presence in Edgar's life and offered him some comfort, the novel focuses more on the internal struggles Edgar endured. It suggests he found solace in his daughter Cathy's love and, perhaps, in the fading memories of Catherine.
Here's what we can infer:
* Nelly's Support: Nelly, as Edgar's housekeeper and confidante, likely provided emotional support and practical assistance. However, the text doesn't portray a specific intervention where she actively helps him overcome grief.
* Cathy's Love: Edgar's daughter, Catherine Linton, provided him with a new purpose and a sense of responsibility. Her love and need for him likely contributed to his recovery.
* Time and Memories: The passage of time and the gradual fading of Catherine's memory played a significant role in Edgar's recovery. The novel doesn't depict a dramatic "healing" process but rather a slow acceptance of his loss.
Therefore, while Nelly's support and Cathy's love likely helped Edgar, his journey towards recovery was primarily internal, driven by time and the fading of his grief.
