<human>: I [20/F] started to sleep with one of my best friends 6 months ago and it ended just over a month ago. Not only do I have to see her [22/F] with someone else now, but I can't fully do no contact because we were never official, we were really, really great friends and we have a lot of friends in common. We haven't spoken much, maybe 3 or 4 short conversations. I spent 3 weeks completely no contact and only recently had those conversations. Whether we speak or not, I feel the same and think about her all the time. I don't know what to do with myself. I used to be a very ambitious person but now I just can't push myself to apply for jobs (I recently graduated from college) let alone get out of bed before 2pm. I have tried to hang out with friends and distract myself but I just keep thinking about her and overthinking what I meant to her and why I wasn't good enough and how she could do this to our friendship if it didn't mean anything. I'm not myself.

Can you condense the text into a few key points?
<bot>: I'm heartbroken, it's been a month and I've just lost all the ambition that once defined me. How do I get it back?
