Bulimia Nervosa is characterized by episodes of binge eating (consuming large amounts of food in a short period of time) followed by compensatory behaviors, such as purging (vomiting, using laxatives, excessive exercise) to get rid of the calories and prevent weight gain.
The pattern you described of restricting food for days, then binging, and then feeling the urge to purge suggests a possible struggle with this disorder. However, it's important to remember that only a qualified healthcare professional can provide an accurate diagnosis and create an appropriate treatment plan.
If you suspect you may have an eating disorder, I strongly encourage you to reach out to a mental health professional or a medical doctor who specializes in eating disorders. They can conduct a thorough evaluation, offer a proper diagnosis, and provide guidance on the best course of action for your specific situation.
Seeking help is crucial because eating disorders can have serious physical and emotional consequences, and early intervention and treatment are essential for recovery. Remember that you are not alone, and support is available to help you through this.
