It's not actually anxiety, it's just the name they've given to the feeling they get when they recieve a reminder of the fact that being fat is not a good thing. "No one will let me in their car! They say I won't fit their seat belts.... Maybe it's not that and that my horrendous body odour is not something they want seeping into their upholstery? Maybe this HAES shit was all a lie? UUUUUHHH muh anxiety"
