Surprisingly, taking the test was a little emotional for me - not almost as emotional for me when I took the Sorting Hat quiz and was literally praying to the powers-that-be I ended up in Gryffindor ('cause I always was sorted in Gryffindor).
Growing up, I always thought of my patronus as my dog Lola, a Jack Russell Terrier. As my best friend who was almost like a therapy dog for me, she was by my side for twelve years (half of my whole life) before passing away last year. She is still a source of so many happy memories, but like many important parts of our pasts, my time with her now has a subsiding grief over a lost companion.
My only other consideration for a Patronus was a duck at one point. Only because one of my hobbies is to swim as much as possible.
It was good a reminder that a Patronus can change over the years, so it wasn't very realistic to have a major attachment to any result. Eventually, I put my big girl Hogwarts robes on and went for it like Harry trying to catch a golden snitch.
This was my result:
My result was a robin. Pottermore doesn't include more info about the kindred animal's meanings, so I dug around. Robins as symbols represent (to people) putting dramas behind them, seeking joy, reveling in a song, and look for new beginnings for growth. A part of me almost wants a hippogriff-like patronus that's a bit of everything: half-dog, half-duck, and half-robin. but a robin suits me too.
