I haven't heard any horror stories besides Airbnb (they closed the Portland office). Bootcamps can be good, but you might want to look at something like https://teamtreehouse.com/. Membership is cheap and you could try that for a couple of months and have a better gauge of your fit in the industry.
I'd look around at companies that are hiring and google the job titles and skills required. Do that for 20 or 30 positions and you'll have a much better idea of what will interest you and what skills to learn.
