I’m never hungry anymore?

[Spiritzrunwild]

Around August of last year, I suddenly stopped being hungry. I literally woke up one morning with no appetite, and it’s been that way ever since. I’m almost never hungry anymore, and sometimes the thought of eating even makes me nauseous. When this first started, I was 14, 5 foot three, and somewhat overweight (around 150 pounds) Now I’m fifteen, the same height, and around 125 pounds. Not only this, but I also get stomache aches more often after eating. Like I said, it literally happened overnight, and I have no clue why??? I haven’t been able to find any answers. I went to the doctor, but he wasn’t of much help. He just told me to eat more, which wasnt even my problem: I just wasn’t hungry in the first place. I have no clue what this could be, and would greatly appreciate some help. Thanks in advance!
