As for weight comments, I am 5'2" and used to be around 115lbs and due to my ADD meds I kept losing weight till I was 103 and decided it was time to go off the meds and talk to a psychiatrist who said that my case was so mild that I ought to be able to easily get away without using meds at all. I still get distracted but I've learned ways of dealing with it.
Well I started putting on weight, aiming for 120 since that was a healthy weight for someone of my stature and this one woman I used to talk to kept saying "Well my son's girlfriend is about your size and 105 looks just fine on her!" Like she thought I should stay where I was or that I was saying 105 in general is too thin for this height.
Um, no. I had been saying that for ME and MY bone structure, 103 was really way too thin and both DH and my bff were concerned I was too thin. I never met the gf of her son but she might have just been built smaller than I am.
I have the same build as my aunts on my dad's side, and my late grandmother, only shorter. They are/were around 5'7" and not curvy but not super slim either.
