Take unopened packages to a food bank drop-off (often found in grocers), feel good about helping, and then buy your favorite items on the LC allowed list you are following. Wrapped foods like popcorn could go to workplace break room, a friend..nothing need go to waste.

Keep your foods simple to start, no recipes, but if having a LC treat would help you get through sugar withdrawal this week, then buy the ingredients and make that. Check the Recipe forum here or at DietDoctor for ideas. DD has enticing photos of what you may want to try.

Once you clean out your kitchen, and stock it with good LC foods, consider working on your thoughts that this way of eating is "limiting". You drank protein shakes and didn't think that was limiting? Some have decent ingredients but popular ones have flavors that all taste of the same chemical stew. Do you like bacon, quiche, pizza, burgers, Asian foods? ... most everything can be made LC.
