normal tsh, low free t4 and normal (low) free t3. what does this mean?

my tsh is 1.38 mU/L, free t4 is 10.8 pmol/L and free t3 is 3.7 pmol/L.

I a have always been a very slim person (5'8 female, 22yrs old, always around 112-119lbs) but in the past 10 months my weight has shot up to near 140lbs and I cannot seem to lose weight through diet and exercise. if anything its gradually creaping upwards. I eat less than 900 kcals a day and do about 7 hours of intense cardio workouts each week.

could i be hypothyroid? im not fat by any means to look at but this is very heavy for me, and i am feeling really depressed about it and bad about myself in general. can you offer any guidance?

We have to know the lab's reference range for the FT4 and FT3 tests. You lab's appear to be quite different than the ones most of us are familiar with. That makes a huge difference. Your results have to be compared against the ranges to tell you anything.
