I'm so sorry for your loss. I know how you feel. My Soshi was like our baby, too. She was 16, and died of a brain tumor.
We had to take extra special care of her because she was diabetic.
So, my husband often said it was like having a child. We had to get home to feed her on time and give her the insulin shot. We didn't go out of town much, even for a weekend, because we would have to board her.
We spoiled her! I'm so glad we did!
When she died, I thought, well, I can now go out of town for a weekend. I didn't really want to, though, and would rather just have her back.
It sounds to me like you gave your kid a wonderful life, too. My vet sent me a condolence and it said something like, 'find comfort in the knowledge that you gave her a wonderful life.' So, I have.
I also cry and beat the bed with pillows and feel so sad I can't remember what happy fells like.
It's been two months, and I now feel more normal. I'm usually a happy, goofy, laid-back person, but as I grieve, I'm completely different.
Writing to others about my greif and trying to bring some comfort to them has helped me so much, and I also journal. I did some artsy things (a painting, a scrapbook) and that helped me, too.
About a month ago, I couldn't stand the quiet anymore, so I adopted two new kids. They are awesome, even though they didn't fill up that spot Soshi was in, they found new spots in my heart. I know, then, that Soshi is still in her spot in my heart, and it never was really empty. She'll always be there.
Just know that it's normal to feel. Your kid deserves your greif, but remember he would want you to be okay, and you will be. It just takes time, and no one can say how much because it's different for everyone.
I'll keep you in my prayers.
Love, brandy, soshi, george, and isaac
