Isn't it more about the fact that they were mean/rude to you and that contributed to you becoming more mentally ill? surely that's the point you want to make - it isn't about concern, it's about cruelty? like, "look what your 'concern' made happen, that wasn't real love" sort of thing?
I don't think they meant to hurt me, they just didn't know any better. I wouldn't have known any better before I developed an ED either. They were not rude, they tried to be supportive by reminding me about "healthy choices". I guess they assumed I just forget sometimes and accidentally overeat. It's not an easy thing to grasp how can someone feel out of control in what they eat when the common sense tells them we are in control of our actions. It might have contributed, but it didn't start my behaviours. I'm trying to be the change I want to see - more understanding, less judgemental, being aware of reasons behind people's actions.
