We always look for landmarks, and in Amsterdam, the easiest for us was the tall tower of the Westerkerk (adjacent to the Anne Frank house). It's located on the Prinsengracht canal -- one of the four main canals, which are laid out in half-circles around the city center. Whenever we got lost, we'd either look for (or ask for directions to) the Westerkerk. Since you're in Jordaan, I'd guess the Westerkerk is visible to you, but if not, pick something else on a main canal. And then figure out how to get to your apartment from that landmark.
Are you staying in an Airbnb? Is your host available to spend a few minutes with you and a map, and maybe a short walk outside, to orient you? If not, a walking tour is a brilliant idea.
And for next time, consider taking a taxi to your apartment when first arriving. We used to try to find our hotel/b&b on our own, but when we're tired from traveling, that can be so frustrating and made us feel overwhelmed from the start. Although after a good night's sleep, a fresh eye on the maps and guidebooks, we always recovered. And you will too.
