I was caught in a similar trap -- made to study for a field I didn't like or have any talent for because I could never make a living as a writer. I surprised them all. I established myself as a writer by positioning myself as an expert in the subject I was made to study. Knowing the odds against getting a novel published I focused on non-fiction. I wrote nights and weekends (after kids were in bed) until I had the credentials needed to get a job in the writing field. Perhaps you can do the same. You would bring a unique perspective to the art world and the combination of your knowledge and artistic talent could make for some very commercial opportunities. Good luck.
