THYROID BLOOD TEST RESULTS WORRIES ME

hello sir/madam

I am 29 years old.. just casually I have tested my thyroid tests at lab,
My results are
T3 (triidothyronine) - 1.70 ng/ml (normal up to 1.8)
T4 ( Total Thyroxine) - 11.24 ug/dL (normal up to 12.5)
TSH - (Thyroid stimulating Hormone) : 1.96 mlU/ml

I really dont know about the thyroid disorders.. after seeing my result i am really afraid by seeing my T3 and T4 are some what near to the border of normal figures.

Should I really think about my thyroid or I am unnecessary worrying about this issue..

Please suggest me..

actually i am worries because, since 4 years i am worried about all the diseases and going for the lab whenever i heard some new disease.
