I agree with what everyone has said. REST, REST, REST. Take a week or two completely off if you can manage it at all.

I had a LOT of anxiety after my injury. It actually can be a symptom of the injury. If it persists, and you find that you are not able to relax around it, you may want to ask your doctor for some anti-anxiety medication.

One thing that helped me a lot was finding guided relaxation and meditation podcasts. I downloaded many of these and would listen to them throughout the day. It gave me something gentle and non-stimulating to focus on instead of getting lost in my anxiety.

Good luck!
