good practitioner to see in the Sioux Falls

Does anyone know of a good practitioner to see in the Sioux Falls area? We have Avera insurance, so if they're approved by our insurance it would be best, but I feel like I'm grasping at straws here. I'm 61, and have had "chronic fatigue" for almost 30 yrs which just gets worse over time. I also have chronic depression, "fibromyalgia" or ME. I've mostly been on my own all these years. We've moved often and I really need some consistent care. I presently go to Avera Functional Medicine, but besides monitoring my thyroid med (which I've been on for 20 yrs with no relief from the fatigue) my CNP doesn't help much. I also have a psyc Dr who monitors my Cymbalta, but I adjust the doses myself and let her know what I need. I feel this is much more than "just the depression". Help, anyone?
PS: I also went to a Dr who does acupuncture under Avera, but the treatments aren't covered by insurance. She says 25% of patients don't respond anyway. That's a rather expensive experiment for someone who can't work much @ almost $60/treatment. I do want to try it at some point...She also wants me to go vegan. I already have eliminated most grains (except rice and oats) plus dairy and soy. I still turn to chocolate for some relief from the fatigue, tho. I can't handle much caffeine at all, or any other stimulants. I have multiple sensitivities and have had many drug failures. Many meds and "natural" supplements, even Vit B12, make my pulse and blood pressure go up, making me feel anxious.
