I'm young, My reputation has gone down the drain with a fairly large group of old college friends, especially with the women, some of the fine girls used to be into me but I've said some things, sort of isolated myself from them, and lacked confidence at the last party I went to with them, they think I'm some weirdo. Very frustrating, I know this post lacks details but I need to know ways to rebuild reputation and how to be more social. Advice?
