No racket sport background players, how do you guys get better?

I started pickleball last January and I feel like di parin ako nagi-improve. 3 coaching sessions na and beginner’s OP 2-3x a week but hirap parin ako maka-maintain ng rally. My partner tries so hard to teach me but feel ko frustrated na siya kasi kahit pag tantya lang ng distance sa bola hirap parin ako. Should I refrain from joining too many OPs muna and just do drills instead? Any motivation could also help huhu. I love this game so much but nakaka-sad rin to feel na napagiiwanan na ko. Thank you 🥹🫶🏻
