Hi, I appreciate that you reached out with your concern.
It’s understandable that dealing with a chronic illness like rheumatoid arthritis can impact your emotional wellbeing. It is a good thing you have it under controlled or at least working on it via healthy lifestyle. These kind of health issues are usually due to chronic stress.
I suggest you to work on your stress and manage your anxiety. You can do the same by practicing pranayamas daily, meditation, and progressive muscle relaxation. If you feel, they still persists, you should consider therapy like Cognitive-behavioral therapy (CBT).
