How to get over the fear of driving in Houston?

Every time I manage to squash my anxieties about driving in this city, I learn about some new accidents that just confirm my fear. Bad drivers, drunk drivers, road rage etc etc. Recently, it was the wrong-way crash on 69 N involving a drunk driver.

I can't even listen to music or podcasts while driving because I'm focused on just getting home safely. I'm more confident on frontage roads, but multilane highways are just terrible. I try to avoid driving on highways as much as possible.

I wish I could completely avoid driving here, but I have no choice. So how do I overcome my fear of driving in Houston?
