I don't see any chokecherry trees/bushes in the wwoded area immediatelly around me.

It could have been in plant when purchase plant. Nurseries do have problems with diseases and viruses so don't totally blame your area for disease now as your plant has disease it can be transfer by your leafhoppers to other stone fruits you may have.

It could also be bacterial spot. Bacterial spot is about a hundred times more common than X-disease and it has many different looks to it depending on the weather during the infection. Look at the picture of bacterial spot on the page below and see how it compares, and look up other pictures.
