Poor thing. I remember watching her on Good Times. She's my age-ish, but I wouldn't want to trade places with her. It's pretty obvious she comes from one of America's most dysfunctional families.
I have not 'let myself go' simply because I have to work so damn hard from the time I wake up to the time I go to bed, It would be very hard for me to gain a substantial amount of weight. She needs to throw herself into something that will keep her busy and feeling fulfilled. I think it is hard to become signficantly overweight if you are A)healthy and B) actively living a positive lifestyle.
