Calm is a collection of some recordings of improvisational playing that I have found personally peaceful and calming. Perhaps it can do the same for you. Relax, find a comfortable seat, and enjoy.
For many years I have tried to do "improvisational" playing and failed. It was all I could do to "fake" it. Recently I found a process by which I could follow a sequence of chords, and if I could just land "within" the chord on the beat, it turns out that the sounds "work out" and are easy to listen to - at least for some people.
