I know the feeling. Our cat passed the week after my stepgramps passed. And its like, when I try to move on, life tries to bombard me every second of every single day. It sucks and it hurts, but its not your fault. The thing to remember is to grieve. Have you taken time to let yourself grieve? To remember him long enough that you can finally move on? Because it may just take longer than most for us to move on, cause I still hurt over Rascal. I didn't know him as much as my stepmom did....but it still hurts. And it was right around his passing that my life seemed to become worse. But I don't wanna take away from what you're saying, my brain sadly gets carried away when I start talkin, I'm sorry. And I'm truly sorry about Oreo, cause it sounds to me that you were really close to him. Probably in ways the others weren't. Like I was with my cat. Its like everything I do makes me think of him, is it that way for you with Oreo?
