Can someone please tell me that it is ok

That I am tired.

I am so tired that I don't want to cook anymore. I want to buy things that are easy yet healthy (prepared like cut up fruit, veggies, precooked meat), instead of cooking. I am so tired from cooking that I am too tired to clean my house the way that I want.

My family tells me I am lazy, and that they were single parents and did it all, but I am not them and they are not me.

I can't do it all. I wish I was a stay-at-home wife (I don't even have a husband lol) but here I am. And I am tired.

Can someone please tell me it is ok to spend more money on things that will make my life easier?
