Welcome, toneMe and lighthope also!
ToneMe, do you know what bulimia does to your health? I know that you proably see any padding you may have as fat that you want to lose, but you are not overweight, so you don't have more than your body needs. Without that padding you will get hurt more easily and be cold all the time, as well as have other health problems. Exercise and muscle building, in moderation, is a good thing. It's interesting that you call your friend delusional. Discrepancy in body image is something that goes along with eating disorders, so chances are he sees you more accurately than you see yourself. Can you help me understand why you see yourself as needing to lose weight when you acknowlege that you are not overweight?
Bulimia is really hard to fight on your own, even when you have friends who want to help you. Does your doctor know about your bulimia? I hope that you will go to a doctor or mental health professional and get treatment for this serious condition. Will you? Like Ozzie said, there is usually more behind eating disorders than just wanting to be thin. There are probably issues that drive you to feel that way. Therapy can help you to resolve those issues and be able to have a more satisfying and healthier life.
I wish you well!
