How do I get over a relationship without jumping into a new one?

I just got out of a relationship with my best friend that I knew of since 2011. I broke up with her because of the fact that it felt like I wasn't there or able to be there in her life. She is childish with abit of problems but what got me was the fact that she cared about me but at the same time it was just words.... It felt like just words.... All I wanted was someone who would support me as I support her but that wasn't the case.... Now I'm just trying to get over this relationship and just wait for someone to come my way and not search for someone.

Was this rhetorical? You kind of answered your question with this "Now I'm just trying to get over this relationship and just wait for someone to come my way and not search for someone.". You wait, you don't go on a wild, desperate search and you learn to become a better you. Be with friends, play games, watch anime, go to school, get a/better job, progress, progress, progress... Above all, never give yourself time to sit and dwell.

keep in mind why you broke up, how even if you wanted it to it couldnt have worked so even the thought is futile think of bettering yourself and your life, so that you can find someone who will give you what you need
