I’m sorry to hear this. Certainly when you’re new to the software, the first drawing is the most difficult because the smallest things can be obstacles. Each one will get a bit easier as you get experience.
There is a lot of free, basic training available at Vectorworks University. If you’re brand new to Vectorworks, go through The Basics to learn core tools and the interface. You could also take the Landmark Essentials online course. You can see the available sessions on the calendar here. There is one running next week.
