Strongly recommend you purchase a copy the original of breakthrough on skis DVD by Lito Tejada Flores.
Still the finest piece of Ski instruction ever produced IMHO.
$30 now on eBay. The music and visuals alone are worth the price of admission! The instruction should eliminate most of your concerns.
Once you digest that will probably direct you to some awesome YouTube material available for free. However, I highly recommend you start with my friend Lito.
I also agree with others here - suggest an equipment check is in order particularly making certain that your ski boots are appropriate and fit well.
I also trust and hope that you spent some time in my beginners Ski tips thread here in the beginner ski forum. Lots of good tips there could be directed specifically at the OP.
I believe Lito also sells his DVDs via his website.
