My top eyelid has been twitching and in the same eye ive had pain sometimes in my inner corner. ive also been having other muscles twitching occasionally in my body. ive also had this sensation of fogginess in my head?

Need to examine: 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!
