If you can go voluntarily and able to leave it might be worth a shot. they may have some ideas and hopefully they will be understanding when you say that him crying stresses you out more. They may have ideas for dealing with it and making it less plus tips for dealing with sam. I jsut re-read your post, no sleep makes things worse, getting through th day seems impossible and trying to keep on top of stuff. Beleive me I know. Maybe by going and getting more rest that will be a miracle cure too.
E is back in bed, I did the leaving him for a min or so when crying and going back in to comfort and suddenly the crying just stopped when out of the room! I went back in and put the dummy in and he has gone to sleep. Now I am worried I have broken his spirit and have threatened the attachment bond. Stupid I know. I didn't leave him long though and it wasn't very long till he went to sleep from when he started. It worked, doesn't make me feel any better though.
