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!

By virtue of your stomach(?abdomen) hurting all day, you should be examined by a physician. Your chest discomfort is most likely muscular rather than due to lung inflammation and anxiety is a common cause of chest tightness. Covid can cause alteration of taste or smell. I would let your MD decide about testing for it. Gently irrigate your nasal membranes with warm clean salt water.
