Maybe you can try ear training first. Start it with listening piano pieces but just pay attention to the melody that the right hand plays or the melody itself. Full yourself with listening music but giving much attention or focusing into the melody and feel the nature of the sound, the feelings that it produce.
Closing eyes when listening is helpful to feel the music. Then maybe you can try playing some of your piano pieces with feelings too. Not the difficult one but play mostly the melodic pieces. Also try watching different piano players and observe how they play. (Feeling the music)
