For the past 3-4 days I have been feeling no hunger, or thirst, I am constantly tired, with a dull fog in my mind, and I dont feel like I am in my body. What is wrong with me? I supposedly have Achalasia, as told to me on an ER trip a few years ago when they had to push a piece of food down my throat , but I have never went to a specialist to get it further checked out or confirmed. I ve been told that the loss of thirst and hunger can be from Achalasia, and I recently have been having much more trouble swallowing food with liquids. But I am not sure about that, or the feelings of disconnection of my body and feelings. I feel numb and like I am not part of my own body. What is wrong with me?
