Tired or Stressed?

This coming Jul would be my 2nd year working in this company. Tbh, I had lost my passion. I was wondering whether I'm tired or stressed? From articles that i read, I should have give myself a long vacation. Besides that, I'm having few symptoms of health problem when i stepped into office. These symptom was caused due to my daily routine or stress? I do not know. 1 thing that I'm sure was I couldn't take stress. I couldn't do all of the things in one time. Yea, i'm not only referring to work. It also happens to study and family as well. :(
