I'm a 25 year old female student and I have had severe post-exertional fatigue for about a year and a half. I can no longer exercise because of this. Routine, daily activities cause some fatigue but prolonged activities (simply going out with my friends and being on my feet for a few hours or dancing) which I seem to be able to handle at the time with little difficulty, is often followed the next day by extreme fatigue and some loss of concentration. This usually lasts approximately 1 or 2 days (I cannot study during that time). I have some joint pain as well (stiff joints in the mornings). I occasionally take alertec (modafinil) to maintain wakefulness while driving (although it makes me feel sick to my stomach!)
In addition, I am hypotensive (morning BP: 80/50; lying down BP: ~110/80; standing BP during the day: ~90/60) as well as some postural tachycardia (HR at rest: ~80; HR upon standing: ~110). I get headaches and feel hypoglycemia sometimes as well.
I am not anemic (was slightly iron deficient with ferritin ~6 due to heavy menstrual bleeding; received shots and current ferritin: ~50). Routine tests have not provided any indication of what is happening (although my 2 hr glucose tolerance test was at 12.9, which is certainly high; cholestrol was slightly high as well); blood work was otherwise normal (thyroid, RBC,...etc.).
I would really appreciate any guidance on what could be causing this.

It's far too early for me to go through this drastic decline in energy. I just want my life back. Please help!
