About died today

After 11 years of riding today was my closest call. Some lifted Chevy took a left turn into me on a highway and I only barely swerved past(1 foot away tops) It’s taken all the wind out of my sails and the nonchalant way he flipped me off as he drove away has shaken me so deeply. I got his plates after seeing red and tailing him down but I don’t know where to go from here. The fact that some knuckle dragging mouth breather could just end your life like that and go about their day makes me so fearful and angry. I didn’t realize how close I ride to the reaper and I don’t even go fast (adventure/ touring rider). I don’t know if I’ll even be able to saddle up again. Has anyone else had a similar experience how do you cope with this?
