When she made the comments I just thought 'what was the point of that?' it was not offering me advice or anything it was purely just pointing out something that was going to make me feel bad about myself. I just don't know why she thought that it was necessary to mention it.
All of this came from a Doctor that was probably a good 30kg heavier than me and obviously didn't take any pride in her own appearance. But yet she found it okay to comment on her patients appearance!
