In life we get known for either having a good or bad reputation, but in reality people get to know us depending on whether we consistently do good or bad. Your reputation can be changed in people's eyes no matter how much bad you've done in front of them by just starting to do good in front of them and then doing it on a regular basis. So don't worry, people may see you as a big loser right now because of how you've messed up, but in time with God's help and some good behavior you can have a very good reputation again.
