You may, or may not, believe in God, but we all go through tough times, feeling abandoned or trapped by circumstances, no matter where we are in our faith journey.
No matter what is going on in your life, pray.
Pray to Jesus for forgiveness, courage, strength, peace, purpose and Salvation. May one of your purposes be to reach out to one in a similar circumstance, and tell them your story of how, with faith in God, you came through and survived.
Let your conduct be without covetousness; be content with such things as you have. For He Himself has said, "I will never leave nor forsake you." Hebrews 13:5
