Same as it Ever Was

Do you ever stop where you are and wonder how the heck you ended up there?
As in, if somebody had told you a few years back that you would be in that scenario, you would have laughed at them?
I felt like that a lot during Mom's fight with cancer. Sitting in the hospital waiting room during surgery, driving Mom to chemo, dealing with Mom's tubes and wires in her hospital room... I looked at my surroundings and was overwhelmed by the fact that I never expected that I would be there in that situation, and I never expected I would be able to deal with it as well as I did.
I guess you don't know what you can handle until you're in that situation.
I find that a lot at work. When I was visiting Mom in the hospital, I was telling the nurse about my job, and Mom said that if you had told her two years ago I would be living in Toronto working with street youth, she never would have believed it. You know... if you had told me two years ago that this is what I'd be doing, I would have laughed in your face.
It happens a lot at work, especially when I am dealing with the mental health and the crises that develop... when a kid got stabbed, when fights break out, when a girl comes in completely naked and I have to spend at least 10 minutes talking her into getting re-dressed, when I have to deal with bed bugs, and disgusting rooms and various bodily fluids, when I get sworn at, and yelled at, when I get told too much information about their sex lives... I find myself pausing and thinking "how did I get here?" At first, it was unnerving, being somewhere so out of my element, now I just laugh it off.
I'm a sheltered girl from a small town. J-walking scares me... I grew up on a gravel road. Whenever we would go to Toronto on family trips, Dad would lock the car doors before we got into city limits, likely afraid that a man with a squeegee would jump inside and mug as at gunpoint or we'd get shot up in the middle of a gang war. That's what happens in big cities, right? I was discussing how I grew up with one of my co-workers after work the other day, and she turned to look at me, and asked "Erin, how did you end up here?" Now, she knows the story of how I ended up here, my botched plans for teacher's college after university, and we went to our Child and Youth Work program together, so she knows about all of that... That's not what she meant. I told her truthfully that some days I don't even know.
Luck? Chance? Divine intervention? I don't know. Was it meant to be, or did I just luck out by ending up somewhere I like? Maybe it was completely random. If one little factor of my life had gone a different way, I could be living somewhere completely different, doing something completely different.
That scares me a little. I don't like the idea that my life is arbitrarily decided by chance... I'd much rather think that I am here because it's where I'm supposed to be. I like the idea that I've been brought somewhere that frequently forces me to deal with difficult situations, but I wouldn't be there if I couldn't handle it.
What about you? Do you ever stop and wonder how you ended up where you are? Has your life taken a clear path to where you are today, or has it been a journey of twists and turns? Is it chance and luck, or is there some sort of plan behind the path your life takes?
