Cadaver lab really isn't that bad. Midway through the first day, we kind of forgot that we were dissecting humans because we were so focused on the task at hand. The part I was most nervous about was seeing their faces, but they are covered all the way up until you start to dissect the face. Just remember that these people made a very selfless decision in donating their bodies to you so that you can have the opportunity to learn. Our professors reiterated that to us constantly to help us get through it. Try to make the most of the experience too! How many times in your life are you going to get to hold a human heart and brain in your hands?
