I don't think your results show you are in robust health. You clearly aren't on your last legs, but your results aren't optimal either.
CRP : For a reference range of 0 - 5, then your result is in the upper half of the range i.e. the wrong half. CRP is an indicator of inflammation or infection somewhere in the body, but doesn't tell you where. You clearly don't have a major problem, but if you could get it lower it would help.
Ferritin : This is quite good. Optimal would be around 80 - 100 for the reference range you've given. Note that high inflammation can have a knock-on effect of making ferritin look rather better than underlying iron might suggest.
TSH : This is too high. Most people with a poorly functioning thyroid feel at their best with a TSH around 1 or even a bit less.
Free T4 and Free T3 : Both of these are in the lower half of the range. Optimal would be upper half of the range, or even top third or quarter. Increasing the Free T4 and Free T3 would lower your TSH.
Thyroid antibodies : Currently negative, which is good. You can have Hashimoto's Disease (aka autoimmune hypothyroidism), without having positive antibodies. Sometimes it can take several tests before a positive result shows itself.
Vitamin B12 : The Japanese consider levels under 500 to be deficient. The Pernicious Anaemia Society recommends a level of 1000 pmol/L to be optimal. Vitamin B12 is not poisonous and can't be overdosed. You would probably feel better with a higher result. If you supplement try methylcobalamin which is already in a form that the body can easily absorb. The most popular supplements on this forum are Jarrow Formulas and Solgar methylcobalamin, 1000 mcg or 5000 mcg per day. The lower dose should be sufficient. Take one a day, stick it in your mouth, and allow it to dissolve as slowly as possible - no sucking or chewing.
Folate : Your result is in the lower half of the range. Personally I prefer to get mine into the upper half of the range, and preferably into the top quarter of the range. You need good levels of folate for the body to process B12. The best form of folate for most people is methylfolate. It is in a form that the body can readily absorb. It is a good idea to take methylfolate in a B Complex along with methyl-B12. The one I use personally is Thorne Research Basic B Complex, 1 a day. It is a good idea to keep the B Vitamins in balance. Having enough of one, and being deficient in others is not a good idea.
Vitamin D : You haven't got a result for this. If you can get one it would be helpful. Deficient or low vitamin D can lead to muscle and joint aches and pains and depression.
It is often noted on this forum that symptoms of hypothyroidism can precede positive blood tests by a long time, maybe even years. In the meantime, try to get your vitamins and minerals to optimal levels, and try to work out what might be causing CRP to be a tiny bit higher than desirable. Gluten? Lactose? Dairy? Low stomach acid? There are probably a few possibilities. If you get everything optimal then your thyroid levels may improve. Your only other option is to self-medicate. It really depends on you, how ill you feel, and how desperate you are.
