<human>: I hear people telling me to just work on me and to make myself a better person but in all honesty, what can I do to escape this looming fog around my life? I know that I need to start going to the gym again to get my mind off of it but the bronchitis that I have now isn't permitting that. 

So mainly, what do I do when I'm by myself? How do I get myself into the mindset to get over her and move on? This girl was someone I wanted to propose to this summer and live the rest of my life with. She was everything to me and now I don't quite know what direction I'm facing anymore. It's not just her that I miss, I miss her family, our friends, her cat, and just everything that came with that relationship as far as comfortability and what not. I just feel so lost and I don't know what to do with myself anymore. It's been an entire month now and I can't seem to get passed this.

Give me the gist of the text in a nutshell
<bot>: The girl I wanted to marry left me and now I can't figure out how to get over her. I need help with how I'm going to move on with my life.
