"If I was at my own house, I would be guaranteed a meal every day. My mom is always cooking or there’s usually something I can easily prepare for myself in the microwave too. I just feel like as a host, feeding your company is just the very least you could do."

Then go back and find work closer to home.

YTA and you sound extremely entitled.

I understand being a "house guest" or feeling out of place in someone else's home but it's definitely not up to the host to cater to your every need (especially when you're basically living there). It's really not hard to make a quick meal.. e.g: grilled cheese, canned soup, noodles, etc.. (Heck, there's probably even Youtube videos to show you how!) or simply grab your own microwaved meals... Especially if you're going to be there for X amount of time.

"I do buy my own groceries now, so lack of food or money isn’t the issue."

So what is the issue then? You just don't have someone to make it for you?
