Well...it might sound stupid...but after reading about many people who lost their yorkies, even when they were babies it gets even worse...
I lost my holland lop a few weeks ago... I was really attached to him and it was a wrong diagnosis, the vet kept on saying he's fine although he had some difficulties breathing and he was sneezing from time to time /I had him for 8 months/

apart from this he was perfectly fine... so after a few check ups at the vet in the last months I had him, he died in agony in my hands...suddenly...a horror movie for 5 minutes which started from nothing

NOW I'M TERRIFIED from getting a new pet and.... eventually losing it
I still don't have my yorkie, I'm expecting it to be born these days.... and now I'm not sure...although I wanted to have a dog my whole life.... I really want this dog, it made my day, even my weeks when my mum said she's getting me a yorkie
It really bothers me, although I care more about the animals' good than mine....my bunny was always first to get all the best, I was thinking about him and his needs more than about my own....
What do u suggest? Shall I risk and take a yorkie as I planned

I'm scared that I'm gonna do something wrong from trying too hard to provide and fix everything needed for my new little baby...or god knows what
