When my husband discovered Ferris, dead after he was missing for 10 days, I thought I would never ever be happy again.
A part of me died with him. I cried for hours, for weeks, for months.
I yelled at people who suggested I would get a new kitten.
I wanted Ferris, not one other cat.
Then I did get a kitten and that helped me. Not as a replacement, Ferris could never be replaced, but Dorian was so helpless and small. We feared for his health in the beginning and that helped the bonding.
He turned out te be one of the sweetest cats I ever had though I will never forget Ferris and the joy he gave me.
Slowly you will start to cope, you will have bad days, some good and one day the grief will hit you enormously, but hey, you have to survive.
Call me when you want/need to talk.
