<human>: For the frist week and a half I couldn't go a night without crying, I knew we had to break up because I just wasn't making her happy no matter how much I wanted to and tried to. I want her back so badly but I need to change first before i even have small chance and i don't know how.

I've started smoking just to be able to stop thinking about her, and thinking about the fear that she may never want to talk to me again. What am I supposed to do, how am I supposed to change. 

After I was finally able to stop crying at night my heart started to burn at the thought of her (this is before starting to smoke). Now just to get rid of that feeling for a little while i have to smoke a cig.

Can you provide a brief overview of the text?
<bot>: I'm feeling really broken and empty and want to change so I might have a shot at getting her back, but I don't know how to change.
