can i get over my hesitation

my trainer has me mainly driving at night, after getting no sleep in a bouncing bunk while he drives. i have to rely on coffee to stay awake which probably doesn’t help the anxiety i get from driving mountain roads with extremely low visibility. i’m driving like 45-55 in 70mph zones because it’s terrifying to be a couple feet from a drop off and have no idea if the next curve is tight or gradual etc. when training is over and i go solo, i’m either going regional or at the very least planning my schedule to where i primarily drive during the daytime unless it’s unavoidable.

i guess the question is does that hesitation go away over time? it’s only my third week in training but it’s scary af under these conditions. trainer says that seeing is overrated and i’ll get used to it, just wanted some outside opinions.
