Hi Arundelle... Most physicians do not perform the correct Thyroid tests to diagnose Hypothyroid which can be a huge factor in depression. I had your symptoms for years and the doc's kept telling me my thyroid was "fine" despite having a slightly elevated TSH test. Usually doc's will routinely do a T3 uptake and T4 by RIA. Some will do a TSH (thyroid stimulating hormone). I finally went to an Endocrinologist who took one look at me and stated, "oh, you have Hashimoto's." He did a T3 by RIA, Free T4 and TSH (which was above 4.2) Hashimoto's Thyroiditis is an immune disorder that can not only cause depression but a host of other disorders. Because it had gone on undetected for years due to several doc's not doing the right tests, I also developed osteoporosis, malnutrition, celiac disease and GI disorders. I had told all the other doc's my symptoms which are similar to yours yet none of them treated me correctly. Be a good advocate for yourself and keep demanding the physicians find out what is causing your debilitating symptoms. Yes, you may only be suffering from depression but there are so many other differential diagnosis's that can explain many of the symptoms you describe... I hope you find a good treatment to improve how you feel.
