Also, "Get turned around" is another expression with the same meaning. But I feel that "get lost" sounds better in this sentence.
You could also add "when I'm" and change usually to always (sounds more dramatic, not necessarily literal).
Ex. I (almost) always get lost when I'm in Ukraine.
To me, this sounds the most natural.
You can add almost if you want to stress that you're not being literal/to be less dramatic. But it's very common to say I always blah blah blah and not mean it seriously but rather for emphasis.
