what to do

i keep asking myself, do i keep believing or do i give up? do i change everything i believe in because for now it has been proven wrong or do i keep fighting because of the slightest chance of impossibility might become possible in the future? why do others get the happy ending while yourself watches from your bad ending? do you have a chance at ever having a happy ending? if you move on would you drop everything at the slightest chance of another beginning? and if there is a slight chance does that mean i should keep things open for that chance or should i really try to move on? oh the things the mind can think of when so lost and broken
