Glad to hear your FI is O.K.
Sorry about your dog. We unexpectedly had to put down our family dog last summer and it still hurts. I thought about her on the train this morning and nearly cried. When I get sad, I try to remind myself that we gave her a great life (especially since she was a stray) and that it was fortunate that we were able to catch her problem when we did, which saved her from any suffering or pain.
Maybe you'd get some comfort making a donation of money or supplies to a local animal shelter. Or maybe you can adopt another pet if/when you're ready and give a homeless animal a nice loving home.
