Sorry there was no one online to talk to you when you needed it. The vast majority of members are UK based and your post was 3am our time so most of us were tucked up in our beds.
I'm really sorry for your loss. It's always a shock when a seemingly fine and strong piggy slips away unexpectedly. I had this with Jemima who hadn't shown any sign of illness whereas her cagemate had an array of conditions for the past 18 months. One evening I went to do their veg and she was in her bed under a pile of hay in her forever sleep.
The loss of a beloved pet is as difficult as any bereavement and you need to be kind to yourself while you grieve. Missing them, feeling low, crying, etc are all normal grieving processes that you will go through.
