Dear Kitten
If all the advice and support you are getting from mumsnetters doesn't convince you that your HV is a liability, then nothing will. Hope by now you are feeling better
BTW, I had tiny tits (relative to most of my BF-ing mates), and never saw hide nor hair of any milk for the first 6 months. Expressing drove me to dispair as I would pump away and produce 1oz at most - I thought, how can this be enough for my baby?!? But of course, I guess I just never let down for the pump, it didn't have a cute face and smell nice.
By the time DS was six months old, he rolled off my tit in a pub garden and I sprayed the lady at the next table Then I knew I had cracked it!! You'll get there, you have determination and now have lots of information to back up your hunches. Take care xx
