First and foremost, you deserve to be healthy and happy. Please, never forget that.
You stated that the effects of bulimia are “not serious or life-threatening” at this time. I would disagree. The fact that you are experiencing physical symptoms is a sign that the bulimia is serious and ultimately may be life-threatening. Eating disorders have the highest mortality rate of all mental illnesses. They are very serious and require prompt treatment.
Sometimes parents may deny that their child is experiencing mental health problems because they’re unclear about how to handle the situation. Perhaps that is why your mother is reacting the way that she is. If that is the case, you need to make it clear to her that your symptoms are real. This can be done in several ways.
The most efficient way is to be honest and straightforward. Request that your mother take you to a mental health professional and inform her that you would like the same type of care that your friend received. If she is unwilling to assist you in receiving professional help, then write her a letter detailing all of your symptoms, or speak to a school faculty member or a trusted relative.
I’m sorry that you are experiencing these problems. I hope you are able to get the help that you desire. A good first step is knowing that help is necessary. Your current challenge is making that clear to your mother. Be persistent and never doubt that you deserve help. It won’t be easy but your health and happiness is worth the effort. Please take care.
