My work days and quality of life in general improved dramatically when I stopped driving and started taking the bus. Two hours total round-trip each day, plus walking about 2 miles to/from bus stops, but I can't imagine ever wanting to drive to work again. Let someone getting paid to drive handle the stress of the road, don't put that shit on yourself. Public transport can be stressful in its own ways, but at least you have some free time to think about how to improve your outlook. When you're driving, you might accidentally cause a pile-up if you do that.

And the lack of ability to "get around" all day is a benefit, let me tell you. Your mind would be thrilled if you said "no, I can't do that" more often. It sounds like your workspace is pretty noisy but your rush-hour commute might be contributing to your bad days more than you think.
