No it certainly is NOT wrong that you love them so much. We all love ours the same I think. But what is important is that you realize that you will love them forever and they will love you forever even if they aren't with us in body, but in Spirit. Shaianne was my heart and soul, I didn't think I could breath without her in my life. Then one day she wasn't. I was totally and completely lost. But as in the case of where people lose a parent, spouse, sister, brother, child. It does get easier. Tho it is very very hard.
I am not trying to change the subject or bring 'it' down, so please don't think that, just something to think about even tho none of us ever ever ever want to.
Please give Simba and Nala big hugs!!
