Can't concentrate at work

I can't focus. Mind is running rampant. I don't know what to do. I have to deliver soon. I can't do my work. I don't know why. I just want to crawl back in bed and stay there. This is really hard. I hate her. I finally realized what kind of person she is, she is evil. I have never hated someone so much in my life. I want her to suffer, i want to smack that smirk and smile of her face. I can't believe I married someone so evil and stayed with her for so long. I am such a fool. The only thing that keeps me going are my kids. without them I would be living in another time zone. I don't want to be around her, I don't any part of her. I don't, i just don't. why does it hurt so much!!!!!!!!
