Not a bootcamp grad, but I just hit my two year mark a couple weeks ago and want to blow my brains out.
Writing internal web applications is the most mind numbing thing ever. It's gotten to the point where I have so much trouble keeping focused at work.
The real issue is that I have no idea what field I'd pivot into.
Are you sure you're not expecting too much of yourself? Keeping focused is pretty difficult for programmers in general, we often need breaks to recharge. Famous Joel Spolsky essay related to this called Fire & Motion:

[But if you're not enjoying the work, that's different. Life's too short for that, find something that you enjoy.]
Of course, there are plenty of jobs that aren't remotely in the cathedral building business, and if that's the case, start networking. Get on Meetup and attend some meetings or hackathons or startup weekends or whatever. Your skills are generally in demand, so focus on getting inspiration for what might interest you, or meeting people that you think you'd enjoy working with, and let that guide your job search.
And don't let internal webapps scare you. Building a "boring" app for a team that does good things with it and appreciates your work can be very satisfying.
It can be a hard road to travel and there might not be a single good answer (only multiple possible answers with varying probabilities).
The difference being in the latter case you've given up all hope and just keep at it?
Maybe. I've been doing this for about 12 years now and, if I were writing typical IT/web dev stuff, I'd move to a different field. Most software is just boring and unrewarding, the money wouldn't keep me if the interest fell away (though I have a family to consider at this point, but that's beside the point.)
Did you take a look at the working conditions?
