Is there any meaning in life after diagnosis?

It's been almost a decade since this ruined my life. I didn't go to college (my academic record is in tatters such that I'll never get into a school of any repute), my employment history is laughable because I always break down, and every day is simply another where I wake up wondering why I'm alive. It was never meant to be like this.

I was a real human being once, one with dreams and a purpose for living. Sure, it always felt a bit dark, and I was always alone anyway, but there was hope. Now with this, every hope feels like it has been dashed. It feels like my life has been ripped away through no fault of my own, and that there is no point continuing this farce.

I ask not out of self-pity, but as a genuine question. Did anyone here find a new hope in life? This illness feels like it takes everything you have and demands more still, so how has anyone found any solace or success in their new existence?
