Most Helpful Guy
Great question. The answer may surprise you but it really is simple. You have to be willing to look beyond how you're feeling right now. As you're feeling terrible, lo loss right?
Remember when you met her? Remember how you felt about yourself at the time, especially when your relationship with her was at its best?
Chances are you were feeling at ease, relaxed and happy. You must practice returning to this feeling. This is how you will find your next, even better mate, or maybe she will come back to you.
But feeling like you do now, like people are judging you etc, nobody that you really want, will want to be with you. We all want to be with somebody that is confident self assured, and happy. So work on being happy :-)
Walk your dog, go on a trip with some friends, go for a walk in the woods... anything to make you feel better!
Stop thinking about her, it will only make you feel worse right now.
Hope this helps.
