I'm so sorry for your loss

I too have lost a Yorkie girl, she was the light of my life and I (and my husband and daughter) were totally devastated. It just left such a huge hole in our hearts and lives when Starr died

My husband insisted that we get another pup right away, but I never wanted to hurt like that again and fought him tooth and nail. Anyway, HE won and got Luna and I gotta say that he was right. Caring for her and keeping her tiny butt alive and eating didn't leave me much time to dwell on Starr's death, and helped me to remember all the good times with her, so that I could smile when thinking of her instead of bawling

We now have Izzy also, because I didn't want her to be an only doggie like Starr was. I learned so much about caring for pups here, and there was SO much we did wrong with Starr, but of course we didn't have YT back then.
Everyone is different, of course, but having a new baby to love really helped my heart to heal, quicker I think than if we hadn't gotten her. The only thing I'd suggest with your new pup would be to purchase a carry bag that has the little strap and clip inside that attaches to the harness so that they can't jump out. They should all have those, and I'd steer clear of any bag that doesn't. Not criticizing at ALL, as I'd have never known that either before I found this wonderful site!
Welcome to you and I hope that as time goes by, your heart will heal
