God loves you and He will give you wisdom in making these decisions. Have you trusted in Jesus Christ as your Savior?
Rom. 6:23 says "the wages of sin is death." Because we have all sinned, each and every one of us owes God death (eternal separation from God in hell). Furthermore, heaven is a perfect place and it requires perfection to enter. This is why the only way we can enter heaven is to receive the perfect righteousness of Jesus Christ which comes through faith. Christ died on the cross as our Substitute and shed His blood as the full payment for our sins. He was then buried and rose from the grave three days later (1 Cor. 15:3-4). The moment we trust in Him alone as our Savior, we are declared righteous by God, possessing the forgiveness of sins and eternal life.
If you can start reading the Bible, I would recommend beginning with the Gospel of John. Also, be sure to pray to God every day. See my links in the comment section below for helpful resources:)
