I suspect personality, skill level, and now aphantasia in your case impacted on fiction writing. Right now, I put personality as the top reason for this. I like comic books and web comics, thus my fiction consists of a series of images and motions in my head, and I don’t really write them down in texts. In this path, I am also not confident of writing a description with a variety of vocabulary. Oh, at the end, lack of time is the main issue, sadly;)
