My life has been shit, and its not for the lack of trying. Anyway, I accepted some things and decided to go on in life with my head down, but due to certain situations life has become extremely stressful, strainful, &amp; I am pushing my limits, depression is omnipresent.I try to excersize and relax on weekends, but no feeling of happiness. These days I am having headaches occasionally, and sometimes broken sleep, I thought may be if I work hard, get things in order, I would get out of it, but it only added stress. Now I don't know what to do, sometimes I feel need to run away from everything or just end this life. 
Is headache common experience in depression, stress, or should I have medical attention?
