Stocking up on groceries

Recently, I’ve noticed that for some reason, I have been stocking up pantry items. I don’t remember doing this before I had a problem with my memory.

If I’m using something, such as a can of non-stick spray and I realize that it is the last one, I will put it on my shopping list. Even if I have just started using this can. I think that I’m so afraid of being in the middle of cooking, baking and I don’t have all the ingredients that I need. I'm so afraid of running out of something and forgetting to buy it and I need it. I think that sometimes I will even buy two of the same things when I shop. I refer to this as my back-up.
