TSH should be closer to 1.0
Thyroid ranges are bogus.
fT3 a little bit below mid-range
rT3 will be blocking some fT3 at T3 receptors
You may be feeling cold easily.
Outer eyebrows sparse?
Please self-eval overall thyroid function via last paragraph in this post.
Elevated rT3 is a sign of and can be caused by stress that weakens the adrenal glands. This can be day to day stress or major stress events like accidents or surgeries. Chronic infections or inflammation [CRP] can do this too. See the thyroid basics sticky and note references to stress, rT3, adrenal fatigue.
Training with low-T, low thyroid function or adrenal fatigue can really make things worse as a whole other layer of stress. Often with young guys who power through training with adrenalin when everything else points to low energy.
Note that most of the symptoms of low thyroid function are the same as low-T and as you described. Many here have the combined effects of both problems. Guys with high TT and FT numbers can feel as you describe with low thyroid function.
TT was mid-range. FT changes a lot during a day with natural guys, so hard to know if a lab caught a high or a low.
CRP is a generalized marker of inflammation. Not cardio specific as often claimed, that was found incorrect years ago. Test again after these 3-4 years.
You need new labs:
TSH, fT3, rT3
AM cortisol [at 8AM please]
Where are you located? Affects diagnostic and treatment options.
Post those body temps ASAP and describe your history of using iodized salt.
The best thing that you can do now is reading the stickies and requesting more lab work.

Evaluate your overall thyroid function by checking oral body temperatures as per the thyroid basics sticky. Thyroid hormone fT3 is what gets the job done and it regulates mitochondrial activity, the source of ATP which is the universal currency of cellular energy. This is part of the body's temperature control loop. This can get messed up if you are iodine deficient. In many countries, you need to be using iodized salt. Other countries add iodine to dairy or bread.
