I’m 22 and just got my first car, so this is the first time I’ve really been able to consistently drive. I get nervous about driving, but I am able to calm myself down enough to be able to get through it safely of course. 

However, I’m terrified of the interstate. I’m terrified of driving at high speeds and passing large semi trailers. People getting mad at me and cussing me out, doing something wrong, or wrecking at 70mph. 

I would appreciate any advice on how I can try to combat this, and be able to become a safer driver.
