broken-hearted

I didn't realize how awful it is to be so broken hearted. For so long, years I just missed my ex and when I finally met somebody new I was so happy. Things blew up and ended terribly. I feel worse than I did about the last guy and it's been 4 weeks since we've talked and i can't take this anymore. My chest feels heavy, I burst out crying at random times, he's always on my mind. I get nauseous thinking about this girl he's dating. It's Friday night and I'm here in bed because all my friends are working or with their boyfriends. I don't feel sorry for myself by any means because I knew I shouldn't have trusted him or even dated him in the first place but I just wish this would pass because I am completely miserable and he's just fine. I don't get how someone can just walk in and out of my life like that. I don't get it
