One thing that would help is to make one big meal so that you have leftovers. For example, I use my crockpot to make this ranch chicken pasta and it literally lasts me for quite a few days just eating on it.
You can get creative with sandwiches, which I do a lot as I prefer to bake them in the oven.
Take stock of your pantry, figure out what you normally have, and research receipes that you can make from them.
And yes, there have been times I've had to roll up toilet paper and use it in place of pads. You do what you have to, so don't ever be ashamed of it.
