just remember when in doubt, an airplane is an airplane. When you get task saturated, fly the airplane and prioritize. Don't be so worried about setting the altitude in the box if you are slow and low on the glideslope. Get plenty of sleep and also throwin a ball with your sim partner while saying your call outs helps because it makes you do it while you're concentrating on something else. Just curious what kind of experience you had before going to the airlines?
