hey guys how certain are we that the 3 days of darkness is going to happen between december 20-25??

im feeling a sense of loss.. like the loss of life.. i feel like im mourning and am upset like upset for others and not have been able to do better.. maybe im just feeling the emotion of my 30 years on earth and how very limited my life was due to circumstance as my birthday approaches.. why am i feeling these things.. is the earth crying and im feeling her pain?? where things supposed to be different this time around?? or are we exactly where we are supposed to be as a collective whole of humanity?? i mean does it have to end in the biblical way or is there a better way to do it?? even though i know i am headed to a better place finally after years of endless hell my heart it seems is mourning for those who dont make it through or something?? i dont know why im feeling these things right now.. can anyone relate??
