Feeling Sick for past few days!

Cheyenne
For the past few days I've been feeling sick to my stomach mainly after eating sometimes before. Yesterday I did get sick after I ate and started feeling better as the day progressed. Today I went out to water my horses and was able to put some of the hose pipe up but in the middle of it I started feeling weak/shaky, I broke out in a cold sweat, I couldn't breathe thought I was goin to pass out and had to sit down and try to get myself to where I could breathe. I also have no color to me I'm as pale as all get out and I have no fever. Help?
