My BMI is between 14.8 and 15. I need help?

I am 18 years old, almost 5'7" and my weight fluctuates from anywhere between 92 and 96 lbs. Looking back now, I can admit that I've been struggling with some type of eating disorder for over 5 years. I have never been officially diagnosed - I am smart and deceptive, and a damn good liar. I've fooled countless doctors and eating disorder specialists into thinking I'm just naturally skinny. But I know that's not true. The physical symptoms of my ED have been apparent for quite some time now - My hair falls out, my hands shake, I'm weak, pale and tired all the time. I have heart problems and my kidney isn't functioning like normal. It is my understanding that a BMI as low as mine is an emaciated state. I think the only thing that's going to help me at this point is inpatient therapy, where I'll be supervised 24/7, otherwise, I'll just continue my bad eating habits. How do I go about getting inpatient treatment? I am not currently seeing any psychologists or doctors about my eating. I live in Canada. I really need help.
