I'm sorry to tell you this, but that's pretty normal. fatigue patients (CF as well as ME/CFS) are routinely ignored, patronized, and even abused (mistreated and verbally/emotionally abused and snide comments made in charts) by physicians.
If you don't have something that shows up in a routine physical (and this disease is not included in the normal screening tests on a routine physical), it takes a lot of patience and persistance to get any help.
Be firm about needing medical assistance, and keep looking for a good doctor (there are some out there--other than one of the actual ME/CFS experts, your best bet for a specialist is usually a research physician, but for a primary care doctor it's hard to tell ahead of time... ask the staff, get referrals, read about them on the clinic's website and make your best guess before showing up in the office, but you'll still probably have to try several before finding a cooperative one)... but remember that doctors have feelings, too. The pleasanter you are about it, the more likely they will cooperate.
I don't know Enlander in particular, but it does usually help to go to an ME/CFS specialist. I thought you were already seeing Klimas, however. I don't think you need both, since I think Klimas is unusually thorough. Some of the other specialists you might need to see several in order to get all aspects of the disease covered, but I would not think that to be the case with Klimas.
You will still need some kind of doctor in your own area. However most of the ME/CFS specialists do not act as primary care physicians (they are too busy just taking care of the one disease in all of their patients).
It helps if you can bring some research to show what tests they can run to find out what's wrong with you (the Canadian clinical guideline, which you can find here on PR, and the Pain Practitioner cover story which you can print, it's hosted at CAA, are both good resources), or ask Dr. Klimas to call and explain.
Good luck.
