You’re being so very brave trying to juggle these two health issues on your own. My heart is aching for you and how alone you must be feeling without a support system with your family.

I know how bulimia can bring on personal shame because it’s something hidden from friends and family. It’s your own personal struggle. Sincerely, you needn’t feel shame or be afraid to talk about what’s happening in your life to your family or your doctor. It can be the first step towards healing.
In fact, your doctor would be a good place to start. They would be an excellent source for setting you up with a counselor to help you overcome this hurdle.
Reversing bulimia is a process and it takes time. Cognitive behavioral therapy, where you learn to change thought patterns, is often a first step. Sometimes there are meds such as antidepressants suggested and counseling to get to the root of the problem.

You’ve been suffering with your eating disorder for over 5 years and you already know that trying to stop is an enormous challenge. This can all be very frightening because of the impact to your health, both mentally and physically, such as fainting with a potential head injury. I imagine you must be feeling pretty overwhelmed with the stress of holding in this secret of both the eating disorder and the CML.

About your CML, what treatment are you taking to help control the progression?

I really feel it’s time you reach out to someone you can trust…family, friend or your health professional. You need a lifeline.
You mentioned you can’t talk to your mom. Are there other family members like your father, siblings, aunties with whom you can confide?
