My girlfriend broke up with me a few days after New Years. Before she broke up with me, while I was on vacation she was talking to other guys and snapchatting them. She broke up with me in text and didn't have the respect to tell it to my face, after three years of helping her and supporting her, etc. I couldn't even get a word in. She said what she said and hasn't responded to anything I've said or returned any of my calls. I'm working on getting over her because I realize that if she would throw me away just like that, than I'm better off without her. I still love her, but I know what is good for me and what isn't. After all, now I see that all I must've been to her in the later days was a penis with money. The thing is that I've been losing too much sleep, and have been getting no more than five hours of sleep every night. I can't get the images my mind creates of her with other guys, and sleeping with them. Everybody at my job had noticed that I look different and have incredible bags under my eyes. No matter how hard I try, these images keep popping into my head. That's one thing of this breakup I can't handle, everything else I think I'll be all right. I just don't know what to do. It's affecting me in costly ways, especially at work. Any advice, please?
