The pattern you cite appears to show you are health focused, which many use as a more acceptable source of fear than general anxiety. Get a checkup with your doc, but follow this with consistent work with a life coach/therapist to learn ways to deal with stress. Life can be better when you have the skills to manage.

It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss if you may be depressed. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated. Drink more water. Wish you good health!

Please have a physical exam to know if you have developed an illness. If not please discuss your medication with your Psychiatrist because there may be a shift in your metabolism
