I am tired all the time. I can sleep at anytime for as long as you will let me. I am even tired when I have had 10 hours of sleep! I heard about chronic fatigue syndrome but I dont know if thats what it is.
I am a 24 year old female without children.

Im actually a suffer awaiting treatment. Its a lot more serious than you think. if you really had it and needed treatment you would probably not be online seeking medical advice.

Check this out, I found this tidbit while studying a specific part of the brain anatomy:

"Lesions in the reticular formation have been found in the brains of people who have post-polio syndrome, and some imaging studies have shown abnormal activity in the area in people with chronic fatigue syndrome, indicating a high likelihood that damage to the reticular formation is responsible for the fatigue experienced with these syndromes."

I found this on wikipedia in an article about the reticular formation which is a major area of concern in people with depression, CFS, etc.

I had a severe concussion 3 years ago in college and never quite recovered and I started to have many many problems, serious ones. I've felt extremely stigmatized because CFS is so poorly understood and is considered a very debilitating disease. Some people are misdiagnosed and some really do have it. I've been to the best hospitals in the East Coast, many many specialists, and its still been quite tough getting answers.

If you needed treatment you would probably have major trouble sleeping, mental confusion, major anxiety and depression, muscle twitching, etc. Theres a laundry list of symptoms, some I don't even want to think about. Your social life would be not existant. You would not be smiling, scared maybe.

Anyways, if indeed you did do some damage to that particular part of the brain causing the extreme fatigue, anti-depressants should help greatly. SSRI's (prozac, zoloft) may not be enough though. there are two causes for depression/CFS, if SSRI's don't wont than a MAOI should do it.

I would suggest looking into Depression, Serotonin, Reticular Formation, and Chronic Fatigue Syndrome on Wikipedia (a credible source). this is three years of research summed into one response. but, like I said if you really suffered from CFS, you would probably be very very ill physically and mentally.
