What if you are in places you actually are not allowed to take any kind of food with?

My other thought is... If your husband doesn't want to take so much food with, doesn't understand it (doesn't want to).
What if I personally feel bad because of that and better decide to eat somewhere, because it's easier?

I am a bit desperate after eating out - I didn't ask reg. the exact content of my food - there was a list of foods inside of my meal and got a sauce with cream and white four - bad taste - my mood got bad immediatelly, and lactose! I can't eat lactose. My evening was destroyed for a small mistake I had made. On that day I already had lunch with. I can't imagine preparing food for one whole day, if not in one place, so preparing food for several days is impossible for me.

Sorry for typing mistakes. I am writing on my mobile phone and can't see what I wrote.
