You've got the chance. As a matter of fact you get a new chance every single day. Start getting back to the person that she fell in love with. Make a little bit of progress today, and more with each following day. Sure, you'll have the steps backwards, but don't think that you DO NOT HAVE A CHANCE, because you do. Don't blow the chance by sitting back and pining away at what you have lost. Pull youself up by the bootstraps and start making the most of each daily chance that you have.
As for best friend... find a new one. Perhaps one that won't let you down. The only one I know that fits that bill is the man upstairs. Second in line would be yourself.
