Feng Shui bed placement?

Ok, so I am learning Feng Shui because I think it may be helpful. I have learned some and now I am lost when it comes to wear to put my flipping bed! It is a rectangle shaped room. Ok on one wall we have the entrance to the bedroom from the kitchen/living room-we shall call this the inner door because its about to get confusing (on one long side) the opposite of the door way is obviously the other long side of the room, in which the far corner diagonal from the door (the place where I am supposed to have the bed) there is a door that leads outside we shall call this the outer door. Now on the (far wall away from the inner door of the bedroom), one short side of the room close to the door is a window. On the other short side closest to the inner door is the bathroom and closet-so where should I put my bed?? On every wall is something not good!
