Everyday, im always tired and i have no energy.. im not depressed... why do i feel so tired, no energy and sometimes my legs feel weak.

Possibility: Hi, even if you do not *feel* depressed you could still have other symptoms including fatigue, loss of energy, loss of interest in pleasurable activities, weight gain/loss, sleep disturbance. You might get an evaluation from a psychologist. Also, i suggest you get a full physical to rule out other medical causes. Be well, .

Deficiency: There are some things that can cause fatigue. Chronic fatigue syndrome, problems with your thyroid, deficiencies in vitamins or minerals. See a physician who can do a proper work up to find out if there is underlying issue. Exercise, get a regular schedule, have daily goals and force yourself to achieve those goals. Good luck.
