Hungry but not hungry?

I have not eaten anything today, its 4pm and I've been up since 10am. I was looking for food but nothing sounded good and I just gave up. Now I'm at the point of no return. The hunger pains are gone and I know I'm hungry but don't feel it. And food is repulsing. Theres only one thing that sounds good and its a frozen meal id have to run to the grocery store for. My fiance is currently working on my car and I hate driving his. I feel like I'm insane. I just need to eat but I can't bring myself to do it. 😭
