Am I not suitable for contacts?

They always seem to irritate me and seem to make my eyes water or strain...as if I have a headache. But, I've been having that feeling for quite some time now even when my contact/glasses are not on or even when I'm resting my eyes. Such as, yesterday I decided to wear them because I just got them in...the new Acuvue Advance Hydroclear....in the mail. I wore them and I had to keep putting drops in my eyes...they were making me feel like my eyes were heavy or what not.

Someone informed me recently that they could be inside out or even upside down...I've heard of them being inside out but not upside down :confused: Should I get the new prescription in my glasses and get sunglasses? My whole point in getting contacts or going back to them was to be able to wear sunglasses.
