Adults with eating disorders

I've been recovered - weight restored from anorexia for aproximatley 5 years. The last few months have been a struggle for me and I've lost a lot of weight. I understand the behaviour itself is unhealthy & I find myself having less and less to give my kids both physically and emotionally, aside from the terrible behavioral modeling. If I could've fixed this with guilt I would have 10 times over. I recently mentioned this to a health professional who dismissed my concerns because I'm only, 'slightly underweight' - I felt totally shamed and misunderstood; you don't have to 'look' like a stereotype, nor do I think it's accurate because I have quite a muscular / athletic build to begin with, if I wait until I do, I won't be able to care for my kids or self or work or do all the things I do. I live in the middle of nowhere and can't really find any support services or assistance to help. I'm asking if anyone has any helpful online resources, books etc that might help get me back on track.
