Why are we living?

Faceing the purpose of our exsistance is hard.. specialy if you don't believe theres nothing in the end and you basicly sees to exsist...
for about 2 years it poisioned my mind and ruined my day to day life i had alot of anxioty over it. the way i basicly over came it is just
to mentally block it out of my head and realise you know what when my number is up my number is up and i lived my life the way i choose
to and nothing else. I am happy i exsist for today i live tomarrow who knows....
