I'm not sure that Photoshop is super user friendly, but you will quickly find your favourite tools. I like to joke that there are at least three ways to accomplish the same goal when editing in Photoshop. It isn't far from the truth.
You'll learn quickly if you practice, guess, take steps backward when you guessed wrong and save your work at various stages. Lastly, try to keep an original version of your edited photo in case you want to start from the beginning.
