Don't get drunk like that again.
Above all, trust in Jesus Christ as your Savior. The moment you do that, ALL of your sins (past, present, and future) are completely forgiven and you are guaranteed everlasting life!
Death leads to heaven or hell, and the only way to get to heaven is to trust in Jesus Christ as your Savior. Jesus loves us so much that He died on the cross to pay the complete price for our sins and came back from the dead (1 Cor. 15:3-4). He promises everlasting life as a free gift to anyone who simply believes in Him for it! No one can be saved by good works. Eternal life is received by grace alone through faith alone in Christ alone (Eph. 2:8-9).
"Verily, verily, I say unto you, He that believeth on me hath everlasting life" (John 6:47).
