Lately i've been feeling extremely tired i feel like i'm not getting enough sleep and i've been feeling dizzy/moody. what can it be?

May be depression: There is inconsistent info in your profile, it states that you are a 23 year male on birth control pills. In any case, your symptoms suggest depression. You should consult a doctor for evaluation as effective treatments are available for this condition. For now, despite feeling tired, start exercising. Begin with daily walk, preferably first thing in the morning.

So many things: From something as "simple" as just significant stress to a hormonal issues can cause what your describe. This is quite difficult to better guide you without a more in-depth conversation. Consider a formal consultation through HealthTap or reviewing this with your primary care doctor. Best of luck
