Has anything in your life changed in that time: new diet, new medication, new washing products, etc, that might be influencing the health of your nail? Did you bang your thumb against something that might have caused damage of some sort? You say that the nail wears down or doesn't grow in: does it look or feel different than it used to? It seems odd, if it is a new problem that you've never experienced.
Good thinking to suggest suspecting a change. I can't think of anything really. Its possibly related to how I file the nail. There have been times (not recently obviously!) when the thumbnail, despite my couple hours of daily practice is just too long and freaky looking. Possibly when I bring it down (always on the side that doesn't touch the strings) I am doing something that weakens it, not sure. I also wonder about the wisdom of putting glue and sometimes silk plus glue on as a prophylactic measure to prevent wear. It might backfire actually weakening the nail. Hard to imagine what else it might be.
