I can only tell you that if you heed the advice that you will truly know that it is only to help you move on. Sometimes the best way is just find someone else to love you and that loves you. You will then discover that there really wasn't anything wrong with you in the first place.
It is ok to want someone to love you and it is ok to want to love someone. It doesn't mean there is something wrong with you unless you let other people convince you that there is. Should I divorce my wife to prove to myself that I can be perfectly fine alone? I say no.
