Did post in chat but now wondering if this is a more appropriate place, had forgotten this section existed 
Name changed for this to avoid outing myself.
Said friend and I were at school together. She has always been one of these people who just seems perfect, brilliant at everything, gorgeous, really lovely to be around. She was bullied by a downright bitchy group of girls in our final year after she put on weight, she wasn't fat by any stretch of the imagination, but had been uber slim before iyswim. It affected her at the time emotionally a whole lot more than she let on I think, and slimmed down gradually over the next few years.
Roughly 6 months ago my friend and her DP split up, they had been together a few years. He got very nasty towards the end, I would class it as abusive in a lot of ways, one of which was calling her fat and making comments about her body in comparison to other women. All absolute rubbish, she just wasn't a stick insect.
Since he left her she's lost a lot of weight. You wouldn't look at her and think she was unhealthily thin, but you would in terms of her body shape iyswim, she's not meant to be so slim. She's seemed very withdrawn and not herself each time I've seen her, most noticeably today, I was hoping she just needed time after the split and she'd get over it but she seems to be getting worse each time I see her. I'm increasingly getting the impression that she's developed a real thing with body image and weight, what she's talking about bears no resemblance to what I'm seeing. I don't want to risk her pushing me away by bringing it up and trying to do something to help as I don't think she has an awful lot of people she's confiding in at the moment, but at the same time I don't think I can sit back and do nothing.
