Hi, welcome to the ehealth forum and I am glad to help you.
You seem concerned by the anxiety and overfocus on your health issues.
The individuals with anxiety disorder often exhibit a variety of physical symptoms, including fatigue, fidgeting, headaches, nausea, numbness in hands and feet, muscle tension, muscle aches, difficulty swallowing, bouts of difficulty breathing, trembling, twitching, irritability, sweating, insomnia, hot flashes, and rashes. These symptoms must be consistent and on-going, persisting at least 6 months, for a formal diagnosis of generalized anxiety disorder (GAD) to be introduced. But you didn't mention any such symptoms.
You must consult your psychiatrist to rule out any psychological factors or anxiety disorders as the definitive diagnosis can be ascertained with detailed interview with your psychiatrist only and the same cannot be made online.
Hope this helps. Take care.
Note: This post is not to emphasise final diagnosis as the same cannot be made online and is aimed just to provide medical information and no treatment suggested above be taken without face to face consultation with health care professional.
