Hang in there man. If this quote by Nietzsche is at all relevant, I wish that it may lead you to rethink, reconsider, re-evaluate some aspects of your life... so that you yourself can believe in the value of your life and your future, so that you can hope and maybe even dream. And remember in your times of crisis, regardless of what you think must be the absolute truth, your life does have value for your peers, for your family, and for us and countless others.
"Distress, whether of the soul, body, or intellect, cannot of itself give birth to nihilism (i.e., the radical repudiation of value, meaning, and desirability). Such distress always permits a variety of interpretations."
Yes, you matter.
