Be sure you know what a solid approach and landing looks like. Then you can ask yourself question on extended downwind, base, and final like "Am I high or low?" "Fast or slow" "Left or Right?" Say it outloud to further emphasize.
Assuming you are using proper crosswind correction you can get down to your roundout.
Upon reaching the roundout, just bring the airplane to a level pitch bleeding off airspeed. When the nose feels like it wants to drop...slowly add the back pressure (the flare) and let the mains touch down. Crosswind landings can be hard for an initial student because you are just getting the whole airplane down with 2 axes...then you add the aileron in to help correct for winds and its a whole nother ball game.
Just keep your head up. Private (in my opinion) was one of the most difficult certificates. Everyone has/had trouble with landings in their private...you'll get over the hump. Good luck!
