Valerie, first of all, you are not alone in this. There are many people who feel the way you do. A lot of this is because we believe that our Salvation is based upon experience, when in fact, it's based upon Faith in Christ. Christ and Christ alone is our Savior, not our experiences. To be honest, you may have a greater testimony and impact than many of your friends do, because you may not have to learn the lesson the hard way. Many people have testimonies of how God got them off of drugs. Or how God freed them from sexual addiction, pornography, etc. And yes, those are powerful testimonies. But in this day and age, I personally believe that a person who can say, "I've never done drugs, or slept with another person outside of marriage" has an even greater testimony. Because Valerie, you are surrounded by your friends, by the media, by the World itself. There are so many pressures placed upon you to go and do what is against God. But when you can say, "God has helped me to avoid these pitfalls," people are more likely going to look to you and say, that is a person who truly lives what they believe.
Keep your chin up and keep striving, even if it seems like everyone else around you has more exciting stories to tell then you. It's more important to strive to do what's right, then to have a story of deliverance from sin.
