I'm so tired of feeling like this, Can you please help me?

I posted this a few days ago Since I have posted this I started eating fresh fruit for breakfast. I have been waking up feeling ok, but within an hour of being awake my body goes right back to feeling this way. I'm miserable, sad, angry, confused, I just don't know what to do. Its leaving me in tears and it has become hard to get through my work day. I was hoping the fruit would revitalize my body to help get through to lunch, but so far it has not helped.
