Is handmade worth it?

Recently (by which I mean a couple months ago), I finished sewing a dress and headdress set that I'd started sometime in autumn last year. Sewing makes me ask plenty of questions, including: why was I born? What cruel force of fate would make my bobbin thread run out like that? Why does my machine sound like the shopping mall version of industrial music? Where the hell did I put that pattern piece? 

The most important question, of course, is the simplest one of all: is sewing my own lolita clothing even worth it? (Spoiler: it depends). In documenting my sewing project, I'd like to take you along on my personal decision making process to see if sewing is the right choice at all.
