I also found Linux challenging the first time I used it... but then again, I also found MacOS difficult and tedious the first time I used it, despite Apple being one of the biggest companies with extensive budget to pour into creating extraordinarily beautiful and user friendly user interfaces.
It's perfectly natural that you find things out of place when you're trying to go against decades of muscle memory. Especially when you expect the new thing to adapt to your old habits, instead of you adapting to the new thing.
Kudos to you for at least trying Linux out, most people don't. If you have any questions, we're all here to learn and enjoy the ride.
