Graphic draw anxiety

The anxiety you feel when making a math test or doing some kind of mathematical homework and you need to draw a curved line in a graphic, because you are afraid you will fuck up the entire graph.

Teacher: Where are all your lines in the graphs? Why didn`t you do your homework?!
Suzanne: I tried to draw them but got graphic draw anxiety everytime I wanted to start.
Teacher: That`s the best excuse ever!
