You are young. You are 16. Might I suggest you find a local Youth group to attend? You can call around your area see what Christian churches have Youth Group meetings. Make sure it is a Bible Believing Church. A few that come to mind are a Baptist, Methodist, Church of God, Assembly of God, New Life Church, and I'm sure there are others. These types of Churches usually have Youth Groups for Teenagers to get together to learn about Christ and be with others their age (peers) who can learn together, suppport each other, and Fellowship with one another in a safe setting usually led by Mature Christian Adults.
Youth leaders there will also gladly help you with recommitting your life to Christ. Since you have said you want to recommit, I am assuming you have been to church before. The best way to grow in Christ is to fellowship with other believers, in person, not just online. Online is great as a supplemental tool but with your ability to get out of your house, going in person would be more beneficial and healthier and then use the Chat and forums as a supplement. It is imperative that we fellowship physically, eye to eye, with other believers.
As for feeling close to God, a relationship with God isn't really about feelings. It is about Faith. It is about having His joy within us and the faith that He is always there even when we don't "feel" Him there. A Youth Group can help you understand this better, too.
If you need help finding a church near you, I'm sure you could give someone here you feel comfortable with the city and state you are in and they would be willing to help you find one that has a Youth Group for you to attend.
