<human>: Can you summarize the given text in a few sentences?

She was, let's say a very big kid, and has taken A LOT of abuse for it, from both family and peers. She's now lost very much wheight, but according to her, not enough. She has the most beautiful, strong and attractive body I have encountered in my 20 years on this earth, but I can't seem to get through to her. Her whole life, and her well being circles around her wheight and belly in perticular. She has a very unhealthy relationship with the gym and gets anxiety if she doesn't go for more than a couple days. 

I want to make her see that she's the most beautiful woman on the planet as she is, and I don't want to be with a toothpick. I'm at my wit's end, please help me with some outside perspective.
<bot>: My SO has serious self-image issues with her body, how do I help her see herself as beautiful as I do?
