There is a beautiful and life-enhancing alternative outlook that offers insight, consolation, inspiration and meaning, which has nothing to do with religion, and everything to do with the best, most generous, most sympathetic understanding of human reality.
Hold to the idea, "I am not the mind, I see that I am thinking, I am watching my mind act," and each day the identification of yourself with thoughts and feelings will grow less, until at last you can entirely separate yourself from the mind and actually know it to be apart from yourself.
Respect your soul: don't keep repeating "I'm going to make it". Your soul already knows that, what it needs is to use the long journey to be able to grow, stretch along the horizon, touch the sky. An obsession does not help you at all to reach your objective, and even ends up taking the pleasure out of the climb. But pay attention: also, don't keep saying "it's harder than I thought", because that will make you lose your inner strength.
