It's happening again......

It's weird and I don't know why, but it's happening again.  The same thing happened last year around this time as well.  I can't eat.  I try to force myself, but I just can't do it.  I tried to eat a persimmon this morning, cut it all up and everything.  Ate a piece of it, and realized I didn't want it.  So I tried to make myself eat another one, and I couldn't do it, I had to spit it out.  I'm hungry, my stomach is rumbling at me, but yet I just can't eat.  I mean, I guess it's not a bad thing, it's not like dropping a few pounds is gonna kill me right.  I've got quite a few to spare, lol.
I guess it's just frustrating.  I'm hungry, and I know I need to eat, but for some reason, I just don't want to.  I think the frustrating part is not understanding why.  And I obviously don't know what to do about it.  I guess the plus side to this is that my grocery bills will be a little lower for awhile.  I still need to cook for my daughter though, so I'm sure I can force myself to choke something down in front of her.  I just don't want to.
Any thoughts??
