I've had CFS for over 20 years and I help lead a support group. I would strongly encourage you to find a support group - assuming there is one in your area. The CFIDS Association can help you with that. They have a listing for all the states.
I have an old listing from when they used to provide them for all the states now all they issue support group leaders is for our state. What state do you live in and what large city do you live near.
I would also encourage you to go to www.cfids.org and go through the various types of information available to familiarize yourself with the disorder such as how it's diagnosed, treatment, etc.
There are very few doctors in this or any other country that specialize just in CFS so it's very difficult sometimes to get a diagnosis. That's why you are given some vague answers. When doctors don't know what's wrong with you, they immediately assume depression if you complain of fatigue. But there is a very defined list of symptoms that a good doctor can use to determine what you have.
Any good doctor - family practitioner - will first rule out all the obvious disorders. There are specialized tests that can help to determine your disorder if CFS is suspected. It's very complex and confusing. Many times doctors confuse CFS with MS and vice versa.
If I can be of further help, you can email me at email@example.com or post a response here.
