Hi, my question is; can you place like a headboard (such as on a bed) in front of your desk? I am assuming your desk is facing a wall? If you can place a headboard to your desk front, then you can place a mirror on the headboard facing the wall which will reflect back whatever comes to you from your unfortunate directions.
I do hope that your desk is in one of your fortunate areas of your home.
Hope this helps,
John
