What happened is happened. You can't do anything about the past except remembering it . And whether it was good or bad we still can move on. I'm pretty sure anyone who knows you personally can forgive you. We're humans and whatever the reason is, we do mistakes. We're designed to do mistakes because we're not perfect creatures. What you did right now took a lot of bravery and it shows how much you really care about your friends here. I really hope all your friends find it in their hearts to forgive you. Lying to someone is not an easy thing but admitting it and show that you're feeling guilty about it an turn things around.
Best of luck Hunter
