Very interesting to hear how things are for you. 14.6 seems impossible as a BMI - but as I have said before, BMI was created to use for groups of people, and now even the medical profession is starting to question the worth of it for an individual.
I have said repeatedly that I do NOT think that every person who is "thin" suffers with an eating disorder; equally, not everyone with an eating disorder is "thin". If people in general seem - to you - to make that assumption, I am not one of them.
I personally was told that becuase I was "thin", I must have anorexia, which at that time, I did not - but I DID have issues with food. I still have those issues - and more.
The hardest part was when I started to "gain" weight - from 6.5 stone at the lowest - even 8 stone made me feel "fat". I do remember though, when I was becoming a more "normal" (for my height) 10 stone, I made the mistake of wearing a lime green lambswool polo neck - and one of the lorry drivers on our site, being over-familiar, said "You're getting a bit beefy" (!!!!!) We were in the company restaurant, and I took his cake and pushed it, wrapper and all, into his cup of tea.
So, maybe a one-off, but people DO comment when people are, in their eyes "fat", eating too much, the wrong thing - or at all.
As I said earlier, the stepmother who labelled me anorexic, based on my appearance, a couple of days later, told me I was a pig for eating a dessert. She is also unfortunately married to my father who, although no Adonis, has always expected his wives to meet certain standards - and even me, as his very part-time daughter. Only a few years ago, we went out for lunch (he and I) and he said afterwards, he would not be seen with anyone ugly (!!!!!! - again). Luckily I don't see him very often (that was 2010, and I have only seen him/them once since - by his choice, but thank the Lord - in 2016 when he, and she, once again, criticised my appearance without knowing anything about me at that time).
