Is the best place to practice driving a parking lot, a large cemetery, or on really dead roads?

I really do want my license but I have a general fear of driving. I started out learning with a friend in a small parking lot, then a really dead road somewhere, I then got some lessons from a driving school, my instructor first took me to a parking lot where we practiced the first lesson, the second lesson she told me to hop into the driver's seat then we went on the road for an hour which was a bit scary. Sometimes my instructor is okay, sometime's they did get a bit aggressive with their instructions which freaked me out and made me more anxious. I have a lesson coming up in a week and a half, I could have had a whole month to practice but then I had to go to Los Angeles, then when I got back I got a really bad case of bronchitis so basically most of my time before my lesson I could have practiced is almost gone. I got a little bit of practice done before LA again in a parking lot but I went from one parking lot to another. I did some driving today as well and built a bit of courage to drive on a road that is pretty dead with some stop signs and stop lights although I'm still very afraid of driving even though it'd be great to have my license. I'm just wondering where the best place would be to practice in a parking lot, a really big cemetery, or on some really dead roads where there's hardly any traffic but there's signs? I went to the area around Brentwood Mall in Burnaby to practice but I don't know where else I could go to practice or if a cemetery or huge parking lot would be better. I actually had a huge fear of driving on the road, and I never wanted to leave the parking lot because I was way too scared and obviously I still am but I'm worried if I stick to a parking lot, I'm not going to able to really know what's going on when I'm on the actual road. I'm also worried I don't have enough time to practice before my lesson coming up and my instructor may freak out again a bit during my lesson.
