Day of Disappointment & Despair...

Yesterday was one of the worst days i had... I threw away $60 buck into the trash by mistake... got shit from my salesperson and had him complaining about me to my boss... i missed my class due to work.... Some plans that i had made a huge twist and changes that arupted my work and plans..now it is not as profitable as planned... My mum heard abt them, she was not too encouraging... Now i am at a loss... Loss of Joy Full of Disappoinment, Loss of Positivness Full of Despair... It makes me wonder that i seem to be a failure all my life.. i have never truely have succeeded in anything regardless work, life , love, goals, dreams.. Nothing at all!! It is my postivness that has brought me so far... but now i think i am starting to lose that positive so i dont know if i can go on dreaming, living... i hate this.....
