I have no advice on how to find a professional field that you can fall in love with, as I pretty much fell in love with mine (mobile dev) on the first go (back in '09).

Just realize that being love with something doesn't mean it is always blissful. I love my partner to a deeper degree than I do with any other person (we have no kids), yet we do sometimes fight and don't get along.

It is the same with any job or profession. Realize this and I think you might become more content with what you do.

Outside of an professional setting I must say that after getting my self an espresso machine two years ago I've fallen in love with making and tweaking my shots.
