I've been told bulimia is an action of self-harm but I would agree with waggiedog (hello back from S/E London btw! ) and I was nearly diagnosed with BPD because my bulimia was seen as solely a form of self harm, for me at least I think there is far more to it than this, I think I may have found a use for it in wanting to cause myself harm but it was never the sole reason, it was always another reason to add to a list and which if it wasn't there, would not prevent me from being bulimic so as much as I can say it can be a form of self harm, it's a by-product of rather than being the reason for.

And also to echo the above; your ED is what it is to you, not to how someone else see's it. Only you will know how things work as vividly and as intricately as you do, no one else can get that same understanding. Hence it's out role to explain to others who try to offer help and support if you want them to help and support you.
