Emergency operation symptoms and conditions

im on warfarin 3.5 mg everyday since nov 2007 because a pulmonary embolism and a second one on jan 2008 while on therapeutic INR. in march 2008 i had a massive bleeding in my ovary and had an emergency operation to remove the blood from my belly. I have serious anemia, 2 years now, and i am feeling that my life is being wasted away!!! I have serious pain on my neck and back and my left arm is really sore i cam barely move it. I have no energy at all and i am surprised of how i have been trying to get extra energy from where there is nothing left!!!.
I am not sure that those symptoms are relted to warfarin, all I know is that I didn't feel this way before!! And I don't really know how bad it is to have anemia and at the same time be on warfarin.

I also want to be me again!!!
