Worsening PTSD symptoms after car wreck

Yesterday after noon I got into a car accident. My two kids and I were traveling like normal and a guy failed to yield to us resulting in a crash. There was a 3 lane road. The turn lane was so backed up that we both couldn’t see each other and by the time we did it was already too late. He ended up getting a ticket for it. His air bag on his passenger side deployed and his car wasn’t operable after. My entire front end is ruined and I can’t open my passenger door because of the front end being smushed. My sensors are going off in my car too. Thankfully everyone involved is okay. That’s what’s most important.

But it’s 4 am and I’m wide awake struggling with my pre existing PTSD. I keep replaying the crash and having intense emotions as if it’s currently still going on. It took me hours yesterday to come down from the adrenaline rush or the fight or flight feeling. I’ve had PTSD prior to this car wreck and I don’t even consider the car wreck to be that bad, just moderate. My symptoms are so much more worse than they were before. I know it’s fresh and it just happened but I already feel myself wanting to avoid driving in fear of wrecking again. I feel crazy, should I speak to a doctor about it?
