19 year old female. I have lost most of my appetite, I ve been tracking what I eat and haven t been able to eat more then 1500 calories a day in the past two weeks. Most days I haven t been able to eat over 1,000. Today I ve eaten around 400 and feel as if I meet anything more I m going to be sick. I m having trouble falling asleep and staying asleep. I constantly feel faint and dehydrated even though I drink over 8 cups of water a day. I ve had a headache constantly for the past week. I m planning on going to the doctor to get everything checked out within the next week.
