I am so sorry for this health concern with your spouse, that carries a heavy stress burden for sure. I would actually be surprised if you weren't feeling anxious. Anxiety shows up in a variety of ways in the body as part of biological design - fear informs the body to defend and protect itself. I would suggest taking some time out for yourself to address this.
