Lost Beloved Pet in Early Pregnancy

Blixy
Three days ago I lost my beloved cat of 14 years. The pain has been horrific. I wake up in the morning feeling depressed and lethargic. Everywhere I look I think of her and her old habits. The loss has been shattering, so much so that it's been hard to maintain the excitement I had a couple weeks ago when I found out we were pregnant. Has anyone else gone through this? Any advice on coping? And will these feelings affect the development of my baby? It's been such a sad few days. I wish I could turn my feelings around but I just can't help how I feel.
