I have been dealing with severe fatigue, muscle tension, burning under the skin for 8 + months now?

I have been dealing with severe fatigue, muscle tension, burning under the skin for 8 + months now. I also had a little bit of neuropathy in both my feet and legs, but I’ve managed to calm that down with lots of stretching.

I have been tested for thyroid imbalance (my levels are fine and I’m on Synthroid for hypothyroidism), Lupus, Lymes, Hep C, Vitamin Deficiencies, and Diabetes. All came back negative/fine. I’m a 47 year old woman — and don’t know what to do next: the only thing I have been prescribed for all of this has been antidepressants–and I can’t take them/don’t feel they are the solution. Who is the next doctor to see about this? Could it be adrenal fatigue — as I don’t handle stress particularly well; maybe I crashed my system? Could it be all premenopausal?

Any advice would be appreciated.
