You are NOT. Read it over and over and over again, until you get it into your head. Every single day is a new start and you can start today. Ask God for forgiveness, he knows your every secret, your every fear, everything. He's going to forgive you because he LOVES you and he wants you to run to Him. He's the one who's going to comfort you in your times of need. Who better than Him can do that? So no matter what you did yesterday or the day before, He wants you to run back to Him. Go right now if you have to. Open your bible, read a verse. PRAY. talk with Him as if he were your best friend. He's there to LISTEN to you and guide you through the right path.
