1800 contacts will call the place to verify your prescription, but its worth a try.
I dont know how much they told you about contacts. Putting them in gets easier over time, just try it for a while in front of a mirror. If you start getting frustrated stop, take a breather for 10min and come back to it. Get angry then trying to stick something in your eye only ends in tragedy.
Oh, and you should probably only wear them for 4 hours at a time, then gradually increase your wear time. They cause a lot of strain on the eyes initially.
