Kayleigh, Shakes is absolutly right. Awareness IS Change. You know about the behaviors that you see in yourself as unattractive. That already is a change. I would venture to guess that when your about to do one of those things that you dont like, you will think about it first and then say to yourself,"Oh yea I dont have to do that anymore, its unattractive", or something like that.
Now I have no room to talk my wife dumped me mostly I think because of my ADHD,(she had a few issues too). Not much I can do about that. So whats the worst that could happen? He could dump you right? Then, maybe the relationship wasnt meant to be? Who knows. I do know that just by identifying those things you dont like about yourself is a very good beginning. You should pat yourself on the back and say Good Job Girl!!!
