Losing Hope

I'm 24 year old male and my girlfriend broke up with. I feel she was the one and I was already saving for a ring. Things in our relationship weren't the best for a few months and I know that was my fault. She landed a great job in Maryland and I followed her with nothing. I just packed up and went. I quit my job here which I was not enjoying.  I was able to find work in MD but it was meaningless to me. Not that it was bad but i have a master degree in criminology and haven't been able to find work for well over a year now that requires a degree in my field or something close to what I would like to be doing.  I became depressed in maryalnd because all I had was her. I wasn't able to make friends because of my work schedule. She worked 9 to 5 and I worked 2 to midnight or later. I became depressed and didn't want to admit i needed help. I started to act different and was really miserable to be around. I started to be immature and rude to her. I started to see it effects when it hit an all time low. By this time I was starting to seek help and I quit my one job that was making me miserable to save my relationship. By this time my girlfriend told me it was to late and she fell out of love with me and hated who I became and who I was. She told me i needed to move out. I'm not living with my parents and have no job. I feel worthless and even more depressed then what I was before. I tried to talk to her and tried to reason with her but she just keeps saying it's over and i know when it's done it's done. I have been seeing a therapist to help me overcome my depression with my job search. I don't know what to do now about this situation I am. Please are there others out there like me. I would do anything to get her back. I have tried to make that known by explaining to her that I am getting help and trying to be more positive and that I am not that depressed person anymore.
