i am in constant agony, this is not a joke; please help me

I am in constant agony. My life is a mess. As a kid I had a natural aptitude for math and science, but I let it get to my head, ultimately ruining my possibility to go to college.

I wasted my life playing video games and watching the television; the natural talents I once had have apathied and worn away, leaving the one thing I was good at behind.

My life has been nothing but a fastly accelerating downward spiral and I have failed to provide anything of with to anyone.
