I was in a roll over accident, as a passenger almost 20 years ago. I still see some of the images like its a video playing in my head. The windshield cracking like a spiderweb from the center outward and the sound it made is one of the most vibrant images, for some reason.

To this day I drive very carefully, always leaving a ton of space between me and the car in front. Occasionally on non-slippery roads I triple tap my brakes to warn off tailgaters, light enough to not engage the brakes, just flash the lights. If that doesn't work, I gradually slow my pace till the either pass or back off. In a snowstorm, I will pull over for them.

Sadly, I don't think these things just go away. You just learn to cope with them. You are only a few months from your trauma, so it's still very fresh.

Can you see a therapist? Also, perhaps at night, try diaphragmatic breathing and progressive relaxation, focusing strictly on your body, right then. See if that helps you relax.

In the morning, if you have nightmares, try writing it out maybe. And as you do, imagine that you are cleansing yourself of that nightmare, getting rid of it, letting it out.

Then try to bring yourself back to the present. What are you going to do today? Focus on that as much as you can.

Again, I haven't figured out how to completely exorcize my "demons" but getting through the day to day is getting easier. I just keep telling myself that ALL that matters is now.
