Neijam, TSH and FT4 are good but low FT3 suggests you aren't converting T4 to T3 well and may benefit from the addition of a little Liothyronine (T3).
Thyroglobulin and peroxidase antibodies mean you have autoimmune thyroid disease (Hashimoto's). Your antibodies are very high so it looks like your remaining thyroid is under sustained attack and probably isn't able to function much. Gluten-free diet has helped some people to reduce their antibodies.
Neijam, thyroxine divides into equal parts T4, T3 and rT3. rT3 is a protection against elevated T3. T3 receptor cells can be blocked by rT3 preventing T3 getting into the cells and rT3 will rise.
