Sounds like you are doing well and It definitely gets easier after a few weeks. At the moment everywhere you go is a new (to you) drop but within a couple of weeks you will start to get drops that you have already done or at least you will have done a drop nearby.
Do try and make sure you have a proper break during the day instead of putting it on break while unloading. I know the angelic drivers on Trucknet would never unload on a break but I found it to be common on multidrop, especially if it was job and knock not hourly pay.
I started on Class 2 multidrop and managed to demolish a metal bollard in the middle of a busy city centre on my first day, and had a audience of maybe 50 people laughing at the clueless idiot driving the truck. Thank ■■■■ it was in the days before youtube and camera phones
