Can you be get sick from being Depressed?

I don't know if you could ever get sick from being sad or emotional. Yesterday I went to a banquet and I was so sure I was going to win one of the nominations as rookie of the year, but sadly, I didn't win. I felt so bad and I felt like crying. I left a while after the party ended and the rest of my night was horrible. I'm still sad at this point and my heads been hurting and my body has been aching too. The thing is I want to sleep and I just slept and woke up feeling really really bad. At school today I was tired the entire time. I feel dizzy and like my heads going to explode. More bad news today just made me feel like punchin the wall, but overall I feel kind of depressed and angry at the same time. I feel very sick right now and I don't know if it results from my emotions? If so, How do i "fix" myself?
