yeah i was in pretty much the exact same spot like a year ago. what helped me honestly was just accepting that i was going to miss stuff and stopping caring so much about 100% copy. once i let go of that it got easier weirdly. also started listening to CW while doing other stuff, like just having it on in the background while doing dishes or whatever, not actively trying to copy just letting it wash over me. dont know if thats scientifically the right approach but i feel like it helped my ear get used to the rythm of it. im up to about 15wpm now and have had a few actual QSOs which felt amazing. still slow but people are generally patient on the cw portions of the bands if you send QRS they'll usually slow down
