Questions about Anxiety

Have you guys ever had anxiety appear weeks after a traumatic event?

My boyfriend’s appendix ruptured mid January and it was really bad. He had a killer infection throughout his whole belly and to be quite honest, it was the most scared I’ve been in my entire life. Worst part was, I had COVID so I couldn’t see him.

He is home now and recovering and the outcome looks fantastic, but I’m now experiencing a ton of weird physical symptoms. I’ve had chills for the last 10 days almost constantly, along with body aches. Dry cough off and on. Thinking maybe everything that happened is finally catching up with me.

This sound crazy?
