Okay I feel so bad not just a little nauseous but BAD...

It seems like every time I stand up I get a wave of nauseousness

I am always tired, I dont throw up, but I constantly feel like I should. I cant even think about most meats either!!!! I mean I feel sooo bad I almost wish I were vomiting just to get the feeling done and over with. This has been going on for almost a week now. I have such a overall bad feeling I cant work out I can barley shop let alone get through cleaning the whole house. I have even dreamt the past two nights in a row that when I wipe theres blood very strange. Also during the day I do not really urinate that frequently but at night I get up 3-5 times to pee. Any one else have any of these symptoms?
