I got tested for anemia and i don't have it, i get proper rest, but i am always tired. i have seen my doctor twice. what else can i do?

Lots of options: Lots of things cause fatigue. Low thyroid, sleep apnea, infections, depression, diabetes and many others. You need a complete history and physical and some blood tests.

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.
