Your test results indicate that you have Hashimoto's Thyroiditis, which is an autoimmune thyroid condition, in which the body sees the thyroid as foreign and produces antibodies to destroy it. Hashimoto's is the # 1 cause of hypothyroidism in the developed world, one major characteristic is swinging from hyper to hypo, which is what you appear to be doing.
It also looks as though you have some insulin resistance going on, with your high/low glucose.
Please post the reference ranges for the T3 and T4, as these vary from lab to lab, so must come from your own report. Also please indicate whether these are Free or Total levels; if your lab report doesn't specify "free" or "FT", then the results will be for Total, which is considered to be obsolete and of little value, though your do appear to be for the "free" values.
