Do you think I have bulimia or anorexia?

you cannot have BOTH anorexia and bulimia!

the criteria for diagnosing anorexia nervosa is:

Refusal to maintain body weight at or above a minimally normal weight for age and height (e.g., weight loss leading to maintenance of body weight less than 85% of that expected; or failure to make expected weight gain during period of growth, leading to body weight less than 85% of that expected).

Intense fear of gaining weight or becoming obese Disturbance in the way in which one’s body weight or shape is experienced, undue influence of body weight or shape on self-evaluation, or denial of the seriousness of the current low body weight.

The absence of at least three consecutive menstrual cycles (amenorrhea) in women who have had their first menstrual period but have not yet gone through menopause (postmenarcheal, premenopausal females).

Furthermore, the DSM-I’ve-TR specifies two subtypes:

RESTRICTING TYPE: during the current episode of anorexia nervosa, the person has not regularly engaged in binge-eating or purging behavior (that is, self-induced vomiting, over-exercise or the misuse of laxatives, diuretics, or enemas)

BINGE-EATING TYPE: during the current episode of anorexia nervosa, the person has regularly engaged in binge-eating OR purging behavior (that is, self-induced vomiting, over-exercise or the misuse of laxatives, diuretics, or enemas).

The binge-eating type is often confused with Bulimia, however in Bulimia the person is not usually underweight.

This is the criteria for diagnosing Bulimia Nervosa:

Recurrent episodes of binge eating. An episode of binge eating is characterized by both of the following: Eating, in a fixed period of time, an amount of food that is definitely larger than most people would eat under similar circumstances.

A lack of control over eating during the episode: a feeling that one cannot stop eating or control what or how much one is eating.

Recurrent inappropriate compensatory behavior to prevent weight gain, such as: self-induced vomiting; misuse of laxatives, diuretics, or other medications; fasting; excessive exercise.

Self-evaluation is unduly influenced by body shape and weight.

These symptoms occur at least twice a week on average and persist for at least 3 months. The disturbance does not occur exclusively during episodes of Anorexia Nervosa.[4]

There are two sub-types of Bulimia Nervosa: purging and non-purging.

Purging Type: the patient uses self-induced vomiting (which may include use of emetics such as syrup of ipecac) and other ways to rapidly remove food from the body before it can be digested, such as laxatives, diuretics, and enemas. Non-purging Type: occurring in approximately 6%-8% of cases, in which the patient uses excessive exercise or fasting after a binge to offset the caloric intake after eating. Purging-type bulimics may also exercise or fast, but as a secondary form of weight control.

So the difference between them is that you can binge-eat and vomit during Anorexia but you have to be underweight, whereas in Bulimia you are not. However you cannot be diagnosed or for that matter actually have both AT THE SAME TIME. You can swap from one to the other but you cannot have them both at the same time.

From what you have written, I would assume you are heading towards having Anorexia because the amount you’re eating is definitly too little! Hope I helped at least a bit :)
