Emotinal support cat

I was thinking about getting a cat bc maybe she can distract me instead of binging/purging/dieting/excersizing, all this foof stuff. bc maybe ill he like AW!! and want to buy her toys instead of pies and tubs of icecream. It mskes me mad when ppl are in the kitchen the same times as me, but she literally cant comment. maybe ill be too embarressed to bunge infrount of my cat idk. I wanted a cat for awhile but Im a messy person maybe she will motivate me to keep the house clean for her
