MCH /MCH/ RDW UNDERSTANDING HEALTH ISSUES

HI I moved to India, about 7 months ago to take on a new job. At the time as a family we were under considerable stress settling the family in, I myself noticed that I was extremely fatigued, and put it down to the long hours in the office, adjustment to a new climate and so on. A while ago, I noticed my memory was really bad, an instance where soemone came into a meeting room and I coudldnt remember meeting them the day or so before. Other things, like watching my family charge around at weekends and everything was such an effort for me. I noticed a lump in my throat so went to the local doctor, he arranged blood tests, her you collect your results yourself and go back to see the doctor. I collected the results but never went back. At the time the results showed my MCH was 32.6*, my MCV 32.6, and my RDW 15.0*. I googled !! and came to the conclusion from poor life style, lack of any protein, increased consumption of alcohol, couple of G&T's each night, and maybe more at weekends, but never so I wasnt in control then it must all be self inflicted. In addition, I suffer alot with abscus in my gums, something I have always been prone to when run down and this had increased. In addition, the doctor check Thyriod we have a history with my mother and grandmother, but I am unable to understand the results,

FT3 = 2.90,
FTE 4= .74,
TSH, 3.22, there is an adult range, being,
FT3 = 2.5 - 3.9
FTE4 .61 - .1.12
TSH .35 - 5.

For two weeks, I have changed my diet, and am on a complete detox but still feel no better, I am taking extra B12, Folic acid, completey cut out alchol out of my diet, but dont feel any better, I have a terrible pain in my head, and my chest things like there is a great weight on it, the fatigue has shifted maybe 5% but not greatly.
Can I please have advise on the above, thanks
