Dear friend, stop stressing yourself about how bad your past was. Your past is already over. God has a wonderful future ahead of you. So, don't keep worrying and bringing up your past. Yes, it "was" a part of you but you don't live in the past. You live now and is looking forward to a bright future.

Offer your past to God and He will handle every bit of it for you. Even those that hurt you, broke you, and made you believe that you can never be better. Please make sure to surrender all of it so it doesn't bleed in your future. Be secured in God that the stains of your past have all been wiped clean through the blood of Jesus.
