Thank you for writing us about your issue. Eating disorders run the gamut. While they have criteria that more specifically characterize one over another, it is not uncommon for a variety of symptoms to be present at different times. I can understand your confusion and hesitation. But you have described enough details here to indicate that the weight loss, change in routine, self-induced vomiting, lightheadedness, lethargy, nervousness, lack of appetite and dizziness are cause for concern.
Although you did not mention your height, it is very likely that your 1200-calorie count is too low to maintain without the help of a professional. You may want to enlist the help of a registered dietitian who can monitor your diet and make recommendations for balancing out your eating, exercise and nutrition. You can find direct help in your area from the American Dietetic Association.
You may also want to work with an eating disorders therapist (available at the top of the page under “find help”) to help with understanding the emotions often associated with eating disorders. I think with the right professional guidance you will be able to orchestrate a plan that allows for positive changes.
While it wouldn’t be possible to answer your question about a diagnosis for you, I do want to respond to your question about men and eating disorders, particularly anorexia. While estimates vary, men constitute five to 10 percent of the cases. Dennis Quaid, the famous actor, recently used the phrase “manorexia” when describing his bout with the disorder.
You have already demonstrated that you are very willing to work hard at bringing productive and sustainable change into your life. I hope this has been helpful.
Wishing you patience and peace,
