Build it up
Whether the people you’ve hurt will give you the time of day or not, building people’s trust again is way important in getting a solid rep back. Look for opportunities to prove you’re not the person people think you are. If your rep is being a bad friend, look out for times you can support the pals you still have, and even other people. Maybe that girl who spends lunch alone would love a buddy, or team up in PE with someone who tends to get left out.
