I like what Sandman said. I have something to add. You can try going back to said social circles w a different attitude. if people are bad mouthing you, and that's not who you are, your actions and behaviors will will speak for yourself. Give people, like strangers, for instance, more credit. Maybe they AREN'T talking about you or even caring what other people say. Are you sure they dislike you? If so, why? What if you decided to repair your relationships with them? We all make mistakes and have a past. Another thing you can do is find a different circle of people who you feel comfortable around.
