GP has referred me for an eating disorder assessment.

I’m scheduled to have an assessment for an eating disorder. I’m feeling discouraged though, like I’m not sick enough to be having this assessment as my bloods and ecg came back normal. Borderline anaemic - one marker off falling into the low range markers and my b12 level was also close to entering abnormal markers. I’m female (34) and weighed 39kg on my last weigh in with her, height 158cm. So my question is, how often does this occur and should I go ahead with the assessment or not considering my labs were ok? I don’t want to be wasting resources if I’m not sick enough to be getting this help. Somebody else likely needs the spot more than me.
