I've always noticed that she lies the most about weight stuff, people calling her beautiful/complimenting her, and things to do with her nether regions like wiping, sex, etc. cause god forbid her BMI reaches 100, she HAS to be at a cute, dainty 99. She's not 600 lbs! She's only 560-570 and it's MOSTLY fluid and she's better because she can wipe her butt and has sex ALLLLLLL the time.
In her mind she's just a slightly pudgy girl with the most adorable face and clothing taste and everyone shits on her for no reason, but part of her knows and is becoming more aware of her size and grotesque appearance because the physical pain and restrictions are impossible to ignore.
It's like a comfort thing to surround herself with uglier people. I remember that video where she was fussing over the lighting making her look yellow and her insecurity was showing through, so she had Becky get right next to her so Becky could be yellow looking too and Amber could compare her face to Becky's and feel better.
I wonder what went through her head when an attractive woman was in the same isle as her in wal mart.... I vaguely remember her talking shit about a girl who looked "slutty" in because she was wearing revealing clothes, and making little jabs towards other women being jealous of HER and how they were ugly. Also this
She's one of those people who are extremely insecure and gets jealous of anyone remotely attractive or better than her, but she's too weak minded to actually take care of herself and her body. She thinks it's easier to surround herself with women who look like Chris Griffin from Family Guy and watch My 600 lb life to create her own warped reality of being this dainty pillow princess. She can eat all she wants and still feel better than everyone else.
