No matter how I tried to bring my mood up, I just can't........

I am very sad, depressed and stressed. This is just the boiling point of every thing. I have done all my best... I just can't believe that all my work was just like a dust that puffed into the air. why is it it seemed that how hard i worked for something the harder and its more illusive. I can't get it.... No matter how I convince myself to move on and just try my luck somewhere, I just can't understand it... this is just so much.. Oh Lord I don't know if I can still pull myself.. sobrang sakit na po kasi..................
