Love the sweater!
I am so saddened to hear about your little Yorkie! The same thing happened to us when our 14-yr old Shih Tzu needed help to leave this world....then two years later, our 15-yr old Llasa Apso. It killed me to euthanize them, but it was more painful (for them) to stay alive. Being a good mommy means making the hard decision to let our pet rest in sleep for their sake, rather than force them to stay alive for our sake.
Oh I cannot tell you how much I feel your pain. I hope you are feeling better soon.
FYI: two days after our 15-yr old Llasa Apso was gone, by husband carted me out to see a box of 8-wk old Shih Tzu puppies, and said "Pick the one you want". I brought "Katie" home...and as it turns out, she is the best of both of our deceased dogs put together in one package. I found it impossible to be deeply sad when Katie was bouncing around needing love, attention and care.
This is Katie, my constant companion and knitting buddy! She's almost 9 now.
