I'm sorry to hear that you have Anorexia. I wish that I could help you with that but I'm not a licensed psychologist. However, if it will make you feel any better, you could at least talk to me about it as one friend to another (Just "Getting it off your chest" usually is therapeutic). Do you think that the day to day stress of your new job (e.g. The heavy workload expected of you or an overbearing, demanding boss that sees you as his/her "Personal psychological punching bag" for relieving his/her own stress from above ["Everybody has a boss."] or both) is causing you to further unhealthily eat even less than before, thus allowing you a false sense that you can "Maintain control" of a part of your life when all other parts of it are out of your control?
BTW - I had a horrible experience before with a monster boss, though my experience caused my Hypertension (High blood pressure) to go up higher resulting in my Cardiologist prescribing me with a higher dosage of
Diovan HCT to get it under control.
