Like Marie says, there isn't going to be a perfect feng shui'ed house. So you're front door isn't facing a beneficial direction for you... you can either move, call a carpenter, or work with everything else and let go of any worries about it.
(or call in to see if a hexagram is applicable to shift your front door a couple degrees. Some it can, some it isn't enough).
If it's not reflecting you in the bed, it should be alright. You could have some beautiful accent color fabric draped around it that you pull over it when you go to sleep - handy in hotel rooms.
As Mayflower mentioned, you are probably just getting interference from electrical or other items in the room. One solution is to do the reading during the day when you can have natural lighting and the light and machines all off. Sometimes this minimizes it, sometimes not.
Yes, water behind you (or an image representing your relationship), isn't supportive. I like those two kids holding hands-type of pictures..but, look at first if that is the type of relationship you wish to have, then look at if the image is being supported with the backdrop or not.
Much Love, Shawn
