PS: You are a very caring and considering piggy mum. I am a planner-ahead, like you; so I can fully appreciate your deapth of care.
Unfortunately, the pain of the loss never gets any less - especially when you have been caring for a terminally ill or special needs piggy for a long time and have built up a much closer bond. But you will find that seeing Cora with Peter is more like the start of a new, very different journey than the end of the old one and that it will give you consolation to see Cora happy and busy again rather than a stab of pain. It is of course always difficult and painful when you have to retrain yourself in your daily routine to accommodate the loss of one you have cared for much more closely but taking your remaining piggies into a ver different direction will actually help this process.
