get into a tailwheel aircraft, that'll really show you how to fly a xwind circuit.
honestly mate, i used to get told stuff like crab it in until your over the fence, then drop you aileron into wind and use rudder to keep it straight etc etc and this only made it worse because i would over think it. Best advice i ever got told was from my current instructors, just fly the damn plane. Look to the end of the runway and do whats needed to keep it centered. no need to over think it then.
You'll get it, like anything in the business, it takes practise
