Why is this so hard for me? Am I losing it?

Why is this so challenging for me? Is my advancing age the reason? We speak of all of these digital skills being a second language, but languages used to be my skill set. I loved the challenge of learning and playing with new languages. Any opportunity to practice was a thrill. No longer. While I continue to work on learning this new language, the terminology does not seem to be being absorbed and I am intimidated in practicing this new language due to my feelings of incompetency. I am discovering that I need to perform multiple repetitions of a task before I have absorbed it, but even then, seem to need to relearn it when I try it again on a subsequent date. I know that if I were more comfortable with this foreign language, I would feel more competent during my journey, less intimidated and more excited by the challenges of making my communications effective. I have tried to immerse myself into this foreign culture and am certainly more competent than when I first entered, but I still struggle every step of the way. If I keep plodding along, can I gain citizenship, or will I always be an alien?
