I am glad you are trying to learn and so moved by Chopin Ballad 1, but sorry have pain in your wrists. I play Ballad 1 and 4.
You may find more help in the Students Corner forum but I will offer some. First, is how to make quick progress in your studies. The following method works for me:

Here is the essence: don't press the keys down with your hands. Instead, use the weight of your body, the upper body controlled by your spine which starts above your pelvis and goes all the way up.
Here is an experiment for you, to show this technique. Sit at your keyboard and press a note, one note, down all the way. Now, use your single finger to support the entire weight of your body this way:
lean forward towards the keyboard. Let your single finger be the only support that keeps your upper body from falling onto your face. See? This is how we apply force to the keys.
As you are playing the keyboard you control the volume by muscles in your back on your spine. You use the weight of your body that way to control your volume. This takes a lot of practice. The payoff is that you can achieve finely graded volume, from pp to f, I think. (Beyond that range is another story, later.)
This will not damage your wrists. It is a time honored technique. As I understand, it was first described by Beethoven.
