Then for treatment of autoimmune disorders such as MS, more comprehensive destruction:

This was also tried for rheumatoid arthritis with mixed results before the development of biologics, and everyone gave up on the immune reboot with chemotherapy in favor of controlling the condition for some patients.

Then there are the prospects for destroying T cells specialized to herpesviruses like CMV (you probably have CMV, near everyone has CMV by time old age rolls around, it's very prevalent) that are thought to cause a large degree of immunosenescence by overloading the repertoire of immune cells with memory T cells for CMV and the like - too many of those and not enough naive T cells to deal with new threats and cancer surveillance. That isn't a going concern yet, but it certainly could be soon.
In my opinion we should be testing all people over the age of 65 for CMV and EBV and putting them on anti-herpies virus drugs to suppress the chronic low level viral turnover that is driving this T-cell clonal expansion.

I guess what I'm asking is, where do I start to cross out other possible causes? Considering so many things can cause fatigue.
Thank you
I'm relatively sure it was simply a bit of depression for me, regular exercise and improving my diet basically cleared it all up.
Definately go see your doctor. Nobody on the internet can really help.
Step two, if you have CFS, is to come up with a plan to manage your energy levels and think about how you are going to live your life. For me, not overdoing it is key. You cannot recover like a healthy person, and often each crash makes your baseline even lower.
Step three, think about how you want to try to treat the underlying issue. Since it's not clear what the underlying issue is, there's a lot of paths here. I was conservative and didn't try a lot of experimental things. I worked with Doctor Jose Montoya at Stanford (http://med.stanford.edu/chronicfatiguesyndrome.html) who is an amazing doctor. He's highly recommended if you can make it to Palo Alto. My health has slowly improved over the years and is much better now than it was say 3 years ago.
Best of luck!
While you wait through what may be many months of medical testing before everything is ruled out, you might try an experiment. Exercise usually helps depression, but usually worsens CFS. Try a bit of gentle exercise, and work your way up gradually over time until you can sustain some intensity. If that improves your fatigue, that's good news, it could be depression, and keep up the exercise. If you feel worse, more depressed, confused, fatigued, with trouble concentrating, that could be post-exertional malaise. Try taking it extremely easy for a few months (maybe many months). Don't do anything that feels like you're pushing yourself. If you start to feel better, if your fatigue and mood start to lift, and you are able to concentrate better, then it could be CFS, and keep up the gentle pacing.
Also, if your fatigue came on after a relatively severe viral infection, that would point to CFS as well.
You will get good help and tips there.
You can also explore the FAQ for some help:
CFS is a pretty nasty condition, so I'm glad they've found something that works. My only concern would be the side effects from Rituxan. It's a well studied drug, but it really knocks down your immune system.
Given that they didn't know what caused CFS (and without further study they still don't know for sure), they don't necessarily have a reliable test that distinguishes CFS from other things that present with similar symptoms. So it's entirely possible that CFS is an immune disorder, this treatment worked on people with CFS, and the remaining cases didn't actually have CFS. It's also possible that some fraction of those it didn't work on have CFS and the drug is not entirely effective, or that some fraction of those it did "work" on are experiencing a placebo effect or a treatment for a different disease that responds to the same treatment.
What this indicates is that, for a subset of people who are chronically fatigued for no reason that the doctors can figure out, there might be some kind of underlying autoimmune reaction that responds to this kind of treatment. If the mechanism is better understood and can be diagnosed, tested, and treated, then it's not Chronic Fatigue Syndrome anymore, but rather an actual disease.
I'm curious, the latest study which is presumably what triggered this story, involved no control group, yet they mention a smaller study from 2011 which did use a control.
If this really does hint at a breakthrough, why did it take so long to follow up on the first study, and why did this one not use a control group?
"According to protocol for the previous randomized KTS-1-2008 study, patients assigned to the placebo group should be given the opportunity to participate in a new open-label study with rituximab. The protocol for the present study was designed to learn about the therapeutic efficacy of rituximab maintenance treatment, for response rates and response durations. Also, the experiences could form the basis for design of a future randomized, double-blind and placebo-controlled trial."
So yes, I think many people who've had CFS would say it's a no-brainer that it was related to an infection. In my case I got "mono" (or glandular fever as we call it here) and it turned into CFS for about seven years. But in the end I recovered and I've been fine for nearly a decade now.
A cure (or even treatments to shorten the recovery time) would be wonderful.
Caution, in scientific journalism; sadly, I'm kind of impressed.
That said, a psychological / psychosomatic component wouldn't undermine its legitimacy in any way. Thankfully, I think we are entering an era in which psychological aspects of ailments are recognized as critical, beyond the control of the patient (e.g. not reflecting a lack of virtue or wherewithal on their part), and treatable.

But my friend is one of the hardest-working, most productive people I have met and is quite wealthy as a result at first of her code, then as a result of her management expertise.
Even so she feels like crap 24/7 and it just won't go away. Nothing helps.
She can be a little hard to get along with, though.
Diet and exercise were certainly where I started. That was seven years ago. Still no joy.
Infections eventually go away. Maybe. Or we treat them with drugs, diet etc. Stress can be reduced, managed, eliminated. We can change the food we put in our bodies.
When nothing works, then what? Keep looking.
