How to apply for disability

It depends on where you live. I f you live the U.S. you can apply for SSI and SSDI on the social security administration's website. You should apply now because it can take a long time for them to process the application. In think that the first thing that you should do is to get a doctor to diagnose you because that proves that something is wrong and you can possibly get better through treatment. The best thing to do would be to go to CFS doctor but those are sparse. Do you have one in your area? If not try to educate your primary on CFS by bringing information about it or find a doctor who at least knows of it. I think that they key to winning a claim is to get a doctor that can write a letter and support your disability claim. Another things is to get them to do tests that show abnormalities because they want medical proof that something is wrong. There's no diagnostic test for cfs but there's a lot of tests that can be done to show abnormalities in the research setting and there's some in the clinical setting. Don't overdo things and try to rest as much as possible because that will give you a greater chance of recovery. I have heard from many people who pushed themselves too hard and now deeply regret it because it  has worsened their condition. You have a good chance of recovery because you've had it for 2 years. The majority of people who get CFS will see improvement in 4 years especially if they don't push themselves too hard.

I meant to say within 4 years. 

It will help a lot if you can get your doctor to write you a letter of disability because that proves to them that your doctor doesn't think that you can work and that you are not healthy. Unfortunately as you prob already know there's no diagnostic test for cfs and most of the tests that will show abnormalities are in the research setting. I'm not an expert but I think that you should get tested for HHV 6, EBV, and possibly some enteroviruses. If your antibodies are high it can indicate CFS and that something is wrong. Some other tests that can be done are stress tests and an mri. I would not do the stress test though because it can make you crash afterwards. It won't take a year for them to process your application unless you get denied and have to keep reapplying. I have heard from others that it helps your application if you are very specific about your limitations. For example have substantial difficulty or cannot drive longer than 30 minutes, lift something over 5 pounds, going shopping without crashing. I would also include your mental difficulties because cfs usually causes a lot of them and this makes it so they can't assume that you can do a non physical/mental job. I would also fill out your disability application for how you feel on your bad days not on your good ones. Lastly for the activities that result in you crashing tell them that you are not able to do them. I heard that some people got denied because the disability people somehow claimed that they were able to do some activities, which the people with cfs were, but they did not understand that they would crash afterwards. Good luck and I hope you feel better.  

If you can, reach out to your family to help you out. I have been trying various treatments in hope that they will help. Ron Davis has been doing great research with the open medicine foundation. I believe that he is most likely person to make a major breakthrough for the disease that will lead to a treatment/cure. His son is extremely sick with CFS.
