Since early this February I feel like my body is shutting down on me. I'm extremely busy with university classes 3 days a week and then working Friday to Sundays. The only day off I have is Mondays but I wake up early anyways to study or work on art projects.

The reason why I feel like my body is shutting down is because I feel tired 24/7, I get an average of 3 to 2 hours sleep because I wake up frequently or worry about the day to come, I cannot eat too much because I get sick, so I eat maybe one sandwich and drink a lot of fluids (trying not to depend on coffee for energy), every time I worry/ stress about something that has not been done my chest starts to hurt, especially the left side is the worst. I've noticed this week that I just look really pale and look miserable.

Also:

I am 20, and was diagnosed and struggled with depression and anxiety throughout my whole high school career. Mid 2010 I felt awesome and happy and was able to stop taking medication. Then in early 2011 it was extremely bad to the point I just didn't care if I committed suicide. In half of 2012 my emotions were crazy because of the medication and not being to keep track of when I took it or if I even took it, so I stopped. Since August 2012 I felt perfectly fine then, no depressing thoughts or thoughts of suicide or panic attacks. But just this past month I've felt really stressed and have been keeping my true thoughts to myself , I'm not thinking about suicidal stuff, maybe a tiny bit depressed but I think I'm about 95% stressed out now.
