I can relate to what you are feeling. That is exactly how it went with Charlie Brown. Now I am enduring not only the painful loss, but the worry of watching all my pigs like a paranoid mother hen, afraid they will all come down with it. It can be so frighteni9ng if I dwell on it. Which is why I try to keep doing things and changing what I am doing so I keep my mind fully occupied. Except for the vigil to watch for signs of illness in the others, I try not to think too much about it at all.
Basically what I am trying to say is, My thoughts are with you through this trying time and I hope that you and the babies will make it through fine in the end. Kindest regards.
