I Don’t know what’s wrong…

Patient: I’m 15, 5 foot 7 and a half inches, and female. I was 135 lbs until one week in the summer I suddenly dropped almost 15 lbs without warning and for no real reason. I’ve been hovering around 122, 125 since and have not been able to gain the weight back. Recently I’ve been experiencing frequent headaches, dull body aches, and fatigue. I haven’t been to the doctor’s because I don’t want to go and nothing is really wrong. if it has something to do with what I eat, I have been a pescetarian for a little over a year, but these things just recently started. I just wanna know: is something wrong with me?

Doctor:
