Passion...?

How does one go about finding one's  passion? Truly, I am asking. I just did a thing on facebook where the video plays and you take a screenshot to see what it stopped on to find out "what you will manifest in 2017". Mine was "passion." I gotta say, right now I'm not sure even what to do to find it, and I just feel discouraged.  I am in a position of employment that I have been in for about less than a year - still in that period of adjustment and learning - and I'm not sold on it. Sure, there are things I like about it, but there are plenty of things I don't like, and the amount of stress I often feel is one of them. And I know some of that stress is just from being new and lacking some of that confidence that comes with experience. But lordy, is it tough sometimes to just suck it up and stick it out, until that feeling of being settled in sets in.
In the meantime, though, I wonder - did I make a mistake career-wise? Should I have stayed where I was before? I was good at it, it was a short commute, paid reasonably well. I liked the folks I worked with - at least mostly, which is as much as can be said for most places I think. :)  That's not to say I don't like the people  I work with now, it's more that it's such a different kind of situation that it's hard to compare the two groups.
Part of me wonders if I need to go back to what I know, what I used to do years ago. Maybe I made a wrong turn somewhere. Maybe I need to come full circle. Or maybe it's just the stress of the newer position making me think  along those lines. A friend of mine contacted me a few weeks ago about a position at her company; I was interested, and it certainly got me thinking, but unfortunately it was a no-go. It made me realize that life is short; I need to find something I enjoy, that I find meaningful...or that at least makes me happier than I feel right now.
Another part of me starts wishing I had a special someone in my life, someone who could support me in my decisions (I'm not necessarily talking financially), who could act as a sounding board, who could help me work through decisions in life. I don't know where this guy is, but I seriously am ready to meet him. I don't mean jump into marriage or anything, but to just have someone around to talk about such things would be amazing.
Ah well, woe is me, right? I've been doing this on my own for so long, making decisions on my own and then hoping for the best...I'm sure in a couple of months I'll be feeling just fine about everything. Or at least mostly so. as I am an accomplished person, successful in many ways, having made some actual good career decisions along the way. It's just the current one that I'm questioning, because it's hard, what I do. It's also rather a lonely job, this position I now have. More so than I could have imagined. (And it's not like I have anyone at home to keep the home fires burning, so to speak, or to need a break from haha.)  Like I said, there are certainly things I really enjoy but holy COW, there are things I intensely dislike so far.
They say you should find something you are passionate about, or that you thoroughly enjoy...How on earth does one figure this out? Or is my mind just too practical to really get creative?
