Profile For Mostly H.

So I'm brand new to trucking, I just joined Prime, so far it's been pretty good. They're interested in making sure I know what I'm doing. It's my 10th day on TNT, and I'm afraid I don't know what to do! My previous PSD trainer was quitting and forgot to check that I knew, well, anything! Long story short, blah blah blah, CDL test pass woo! Now I'm on a truck where I am with Harvey Dent! (Two face for you non-nerds). The guy is fairly chill on most things, makes sure we get showers (whew!) And has rules about no religion or politics (good good). However when it comes to driving this guy is the fragging devil! Apparently I'm his first student, EVER! I wrote it off thinking I could do this. But even though we're getting miles done and I am slowly learning, it's wreaking merry havoc on my mind and body. He'll show me something once, like a backing maneuver they don't teach in school (but maybe they should, I'll suggest when this nightmare is done) then act like I'm supposed to get it out. The first try and if I mess up (which c'mon I'm new and super nervous all the time) half the time he acts like I'm supposed to be a team driver that can do no wrong, will be quick on the draw with EVERYTHING, including break time, then he'll teach me something like he should without yelling. I'm mainly driving at night, usually over mountains, and everything is breakneck pace 10 on, 10 off. He rarely takes the time to give me practice. Just one poorly done attempt and "you ****ed up, move over!" Sometimes I feel like I should just get off the truck and call Prime (not necessarily in that order) tell them this guy is not ready to be a trainer get me someone who can teach! But at the same time, I don't want to have to go through an even worse butthead (curses! I cannot curse properly!) Or worse have to start over again, ugh, because nobody can give me a definitive answer regarding my miles. That's if I can get a word in edgewise. Seriously this guy talks over me constantly, it's almost always a one way conversation. Seriously I'm getting burned out on trucking before I even begin. How should I proceed?!
