Anyone else struggles with food anxiety and shame?

I have GAD and one way it manifests is I NEED to have more than I actually need of anything or im constantly stressed about when that thing is gonna run out. That unfortunately also manifests with food shopping. I need 1 chicken? Lets buy 2 just in case? Already have 4 bottles of oil at home? Let's buy one more, you never know. I dont know anyone who is skinny and does this. But for me I often feel judged when I shop so much. Like Im an insatiable glutton. Anyone else?
