I'm sorry you're going through this, especially since you haven't been able to get a diagnosis. Has anyone mentioned fibromyalga to you? That's a possibility. Also, there are some people who do have autoimmune diseases but have negative blood work. Sometimes, if the symptoms are obvious enough, a doctor will treat the patient with negative blood work just as if the blood work was positive. Don't be discouraged. It takes time to get a diagnosis. Ask the rheumy what your next step should be. If all else fails, get a second opinion. Good luck and best wishes.
