I'm gonna expand on the whole "thin, ugly girl" thing.
Fat girls are very limited in what you can do with them. Anything involving physical exertion is out of the question. Hiking, biking, heck even getting somewhere at a reasonable walking speed is straight out. So either sit at home and consume whatever the monitor has right now, or go out to do things involving sitting and eating. Which brings me to the next issue:
The thing about your 95kg girl. She's 95kg now. Who knows where she is in 2 years. in five. Your ugly girl will not get any uglier in the next years.
You can come to terms with how she looks, but try coming to terms with her weight if that weight keeps going up.
And the last thing: There is no huge ugliness acceptance movement she might reveal to be part of and ruin your life over it.
