Hi,
I think it is great that you are recognizing that you need a change in your life, and that you need to rely on the Lord to receive forgiveness. That is a great start. The thing is the Lord knows your heart and knows everything about you. He knows you are searching for Him right now, so if you just call out to Him and welcome Him into your heart, He will hear you.
You don't need to read the bible for a specific amount of time in order to know the Lord. When you welcome the Lord into your heart and mean it with all sincerity, your sins have died on the cross with Jesus Christ. I know that I started out where you are right now. Knowing that I needed a change and not entirely sure what to do to be forgiven. We all start out that way.
Mark 10:15 says "Assuredly, I say to you, whoever does not receive the kingdom of God as a little child will by no means enter it". I find this verse very encouraging, that we all start our faith in the Lord like a child. Over time we build our relationship with God and our faith will grow along with it. Children trust in what they are told and take it to heart. This is the way we should approach the Lord.
Romans 10:9-13 says "That is you confess iwth your mouth, "Jesus is Lord," and believe in your heart that God raised Him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved. As the scripture says, "anyone who trust in Him will never be put to shame." For there is no difference between Jew and Gentile- the same Lord is Lord of all and richly blesses all who call on Him, for, "everyone who calls on the name of the Lord will be saved."
