Do not stress, your landings will come back. I find the Rad Alt aural call-outs to be most useful when landing
Landing by ear... And then comes the (inevitable) day where you fly a plane without those Rad Alt callouts. Ouch!
Anyway, i have found that throughout my life as a pilot i had phases of great landings, no matter the conditions, and phases where every landing was, well, not really nice... Thank god i did all my off airport landings in glider planes
