Briefly, but I realized that the creative satisfaction of the whole thing came from being able to do everything myself, so giving that up would have made it pointless to me. I feel bad about it because it's definitely a bit of a narcissistic take (praise me, for I can do it all!), but the truth is that I was also discouraged by the mistakes I made in the research process, and how mean some of the commenters who pointed them out were.
I started to get a lot of anxiety about the whole process, and realized that I would have had to put even more effort into it ok top of my full time job, which further cemented my choice to just run away from it. I periodically feel really bad about it. Hopefully some day I'll win the lottery and I'll be able to make another episode. I actually have the script for episode 3 all done: I wrote it on parental leave, but that also didn't last forever!
