whats a good weight for someone who is 5'6"?

I'm 5'4" and a 110lbs

Sooo...
at least 120 ._.

one of my best friend on fanpop it 5'10-5'11" and 170.

Has your doctor یا parents کہا anything to آپ about it? Are آپ otherwise healthy; ie, you're sleeping enough and active and able to get through the school day?

You're still growing, so I'm guessing that your weight will be in flux for a while longer. I'm the same height as you, but I'm ahem, way older, and I'm 140 lbs., and that's kind of the heavier end of the spectrum.

I wouldn't be too concerned unless you've been told otherwise. As a contrast, my daughter is 17, is 5' 10" and weighs 100 lbs. She's been told to eat مزید than once a week.
