Can someone please help me with my numbness problem?

3 years ago i had my heart broken by some ugly *****..due to this i became intensely depressed in the summer of 2008 it was the darkest time in my life. Every day nothing but sorrow. Then one day in the fall i woke up and i just couldn't feel any emotions anymore. Now it's been 3 years and was i able to move on with my life and put the entire heart break behind me 2 years ago...but the numbness hasn't gone away. I've lived day by day for the past 3 years with no emotion and everyday seems like a dream..there's been lots of girls and opportunities that I've let pass up due to my problem. I have found a name to my disorder its called Depersonalization. What can i do to fix myself?
