In my early stages of training I had real problems with landing. It delayed my 1st solo by about 5 hours.
If the approch is good, the flare becomes a lot easier. If you are set up correctly, at the right speed with the right rate of descent, and central on the runway all you have left is the flare and plenty of time to think about it. It's when you're not quite central, or too fast, or too high that thinking about flaring becomes an nightmare.
Once your set up correctly I always look to the end of the runway, then use periferal vision to see myself sinking. Then bring the nose up to protect the nosewheel and a nice gentle touchdown follows.
It may be worth spending some time just sitting in the aircraft on the ground so you get a feel for how low you are with the wheels on the gound. Then it is easier to set up a flare attitude where you don't land nose first.
As has been said before, landing one wheel at a time in a cross wind is fine, and many consider it good airmanship to do so.
