Humiliating. Almost 22, pregnant, and still cant drive.

Well the title says it all. Im almost 22, im due in about 3 weeks and i still cant drive. I was so eager when i was younger to drive.

The fear started at 15.. My mom had a boyfriend who was abusive toward me. One day i went to get some food with him. He ended up getting drunk and having me drive back home. I was scared because it was raining really hard and we were in a "cliffy area" lots of high points of rock and drop offs. I ended up sliding over the edge of the cliff. I dont even know how we got back on the road but we did. We almost died. I felt horrible after that and scared. My mom eventually left him but she would never try to teach me to drive. She did once, but my anxiety was so bad she would just scream at me until eventually she stopped taking me. My 17 year old sister is driving because her dad taught her and its humilating for me... i want to learn and thankfully my bf is going to teach me. Any tips to manage my anxiety?? Any driving tips to begin with?
