i also got it and i know how hard it is, what i recommend doing is having a slower pace than the rest of the osu community without this.
even though i have joined a week and a few days ago i did have this realization before hand so i kind of just started out on easier rhythm games like fnf and shit, and then when i felt like i progressed enough i moved onto here.
what i am currently doing is this:
1. practicing MULTIPLE beatmaps with an order - this order can be whatever you please at the very start but you must stick with it through out until you beat the next star difficulty.
2. once you beat a star difficulty practice the one you just beat with a new order of beatmaps, if you do not have enough beatmaps then just install more.
its quite a simple step in progress and i found it quite helpful, i just recently beat a 4.6 star as a new osu player following this method.
