A woman's questions

I just started a couple weeks ago and I am so unsure about all this now. I went through the schooling while working full time. I got my license day after school ended.. I then went straight to orientation a couple days after getting license. I have been on truck couple of weeks with someone with whom I thought was a friend and would train me. But all she does is complain about the money she is losing. She is the one who offered to train me since her husband just retired.
Is it wrong to feel pissed off or disappointed? I mean she has made me feel like this whole thing was such a burden to her...
Was everyone's first experience out here crappy and then it will get better? Should I go back to my company and ask for new trainer? Should I turn her in for some of the things she is doing? So lost about all this. THIS is all new to me. NOT quite sure what I expected.

 

I will be doing teams and she was supposed to be my team member later for 1 yr until i.could get on the truck I truly wanna be on...
Now I'm stuck... I'll lose a friend and don't know how to report the bad stuff to the company without her retaliation....

 

I was brought into this company as a trainee by her so that way it gave her a yr to find a good co driver since her husband retired. I then get to go to the truck I want. But with all the bad stuff she is doing... I dont feel its right to stay on her truck. I have a set standard of morals and values even driving..... I wont cross.
I just feel bad... she is a friend but where I used to work( office job for gov't) it was all black n white no grey area.
Here it seems like 50 shades of grey...lol
