Abnormal weight lost and height growth

Patient: 2 Questions:2- I have been losing weight in the last 2 months, although i eat normally, even better than last semester.My weight can be a yoyo sometimes, but this time I am freaking out, since I do not think I am sick. I drop one size in pants, and my breast got smaller too. I also lost my curves. What is it and what should I do?1- these last couple of months, I have been growing up in height again; although i am already 23 year old. and I am 6 foot tall for 150pound. Is this normal? How can I stop growing up?Thanks
