<human>: I'm a 17 year old female, 5'1", 125 lbs. I am a fighter which puts a lot of pressure on me to lose weight. In less then 2 months I have lost almost 15 lbs. 
I do get very fixated on my weight, weighing myself probably 4 times a day. I still need to get down to 118 for a fight, but sometimes I feel like I am getting an eating disorder.  I guess I am just wondering where the line is drawn in between eating disorder and a good dieter. Can anyone relate? or have idea to help with getting super obsessed on weight?

Can you give me a shortened version of the text?
<bot>: I get pretty obsessed with losing weigh and don't know if it's normal. I don't know where to draw the line.***
