Neck discomfort?

I went on a Florida road trip with my family. I had a lot of uncomfortable nights there filled with anxiety and stress. When we returned, I started noticing a lot of neck pain and discomfort. My neck felt very tight. I started seeing a chiropractor but he would often go out of town so I wouldn’t see him regularly. He said I have a pinched nerve and that every time I get anxious I make my neck tighter. He always does some adjustments and tells me to ice and stretch. I feel a bit better but i still find myself extremely anxious and nervous to stand up for too long. I feel like I’m very forward and like my head is heavy. Have you ever experienced anything like this? What did you do?
