Hey, today has been quite a different day for me in a few ways i cant seem to understand. i spent my day feeling very fatigued and close to fainting, i kept shaking and i narrowed it down to sugar and blood pressure but it wasnt either?

Get med-check up: Besides what you have checked out, your symptoms can be due to intense anxiety. Are you worried or stressed about anything?. Try to relax and take a walk outdoors to relieve your anxiety. if your symptoms persist, go see your family doctor for further evaluation and treatment.

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!
