Is 12:00 am too late to eat if you're starving?

I haven't been eating lately...idk I just haven't been hungry. I'm very anxious and stressed about something right now so I guess thats why. Anyway, I've only eaten maybe one full meal since Sunday and it's Tuesday night. Yesterday the only thing I had was a slice of pizza but didn't eat the whole thing because I just wasn't hungry. Then this morning I didn't have anything, and I skipped lunch, but my mom, being paranoid, made me eat because I was getting weak. So far today I've had half a chicken and lettuce burrito, and a couple bites of cereal. I'm starving. But it's 12:00 am. Should I eat?
