Excuse me, with a height of 159cm and a weight of 116kg, is this considered a fat girl?

Doesn’t belong! Let me convert it for you: We use the BMI index to measure it. BMI = weight (kg) ÷ height (m)?, which is an international standard for measuring the body's fatness and thinness and whether it is healthy.

Your BIM=58÷1.59?≈22.9. Looking at the picture, according to the standard, the normal value of the subspecies is 18.5~22.9, and the Chinese standard is 18.5~23.9, so you are in the normal range now, just maintain or be slightly thinner.
