Lost my appetite

I started this week by being in bed for 2 days cause I caught influenza
On Wednesday, I still not feeling well but I pushed myself to go to office
On Thursday, I worked at office for almost half day
After that, on the afternoon, I went to my brother's opening celebration of his new business
But I didn't know why, I can't eat anything, I have no appetite at all
So I just drank es dawet and eat bubur ketan

Untill today, I still lost my appetite
Today I just ate half bread, es degan, and 2 pieces of chicken
And I don't know why, I just feel sooo bad mood all this week
