Some foods are just triggers. Resist once at the store and do not buy. Then you don't have to resist a million times at home. Things with wheat or sweet just set me off and here comes the blood sugar wackies. Sigh.
Sounds like popcorn shrimp is one of yours. Is it the breading?
And next time? Round file. Destroy it, step on it, make it unfit to eat. Blender, fling in yard, def trash.
Be leery of thoughts like this:
"whatever, eat the whole bag. You've already messed up and it will remove the temptation."
Do not talk down to you.
Do not dismiss the struggle -- it is HARD and you ARE trying. Pat yourself on the back for the effort. Don't "whatever" it. Don't punish yourself.
Do not dishonor you and treat your body like a trash can. If you want to trash it, throw it OUT into an actual trash can.
OWN that temptation and YOU rule it. YOU stop feeding it, YOU trash it. YOU stop buying it. You stop thinking it and giving that temptation so much leverage with you.
Don't hide from it, don't let it rule you.
But def don't talk down to you along the way while learning to deal with temptations like that. It's only a trigger food. YOU are a valuable person. Worth way more than popcorn shrimp or whatever trigger it is.
