when I am glowing with the enthusiasm of success, there will be none to participate my joy; if I am assailed by disappointment, no one will endeavour to sustain me in dejection. I shall commit my thoughts to paper, it is true; but that is a poor medium for the communication of feeling.
The sentiments expressed by Walton mirror those proposed by Anthony F. Badalamenti in his article, "Why did Mary Shelley Write Frankenstein?" (http://search.proquest.com/docview/756918789?pq-origsite=summon)
In the article, Badalamenti cites Shelley's estranged relationship with her parents as a possible driving force for the novel's creation. Shelley's birth-mother died soon following her delivery. Her father later remarried to Mary Jane Clairmont who, "showed little regard for young Mary’s gifts or for the breadth of her interests" Furthermore, Badalamenti says, "Mary saw her stepmother as distancing her father from her and as coming between them." This distance ultimately left a thin hope for connection through the craft that Shelley and her biological parents shared: writing. In Badalamenti's words, "Mary Shelley was deeply attached to her parents’ works, the one deepening her tie to her father and the other among her few means of knowing her natural mother."
Considering Shelley's experiences, Walton's thoughts could demonstrate how, despite trying to close the gap between her creators through common interests, her parents' emotional and physical absence made it impossible to reach them. In that sense, Walton's angst would be an expression of Shelley's as well: lamenting the inability to share success or grief with another.
