Why there are times that you hate yourself?

Generally, most people suffer from this. They're confused or pressure. Their environment may have something to do with this. I would say, there are some instances that maybe just maybe we forgot to take our vitamins. I have read a study that our body needs some essential vitamins so that it will work properly, especially our minds. This is just my opinion

yes there is times that i hate yourself , you know when i feel i am not useful for myself or for others i feel the same ,, BUT lets to be happy .

becuse sometimes it feels like I can't do nothing right or I'm having a bad day!
